  • Pete, I was refering to the rules, yes, but simply because I don't know how the ranking system works.
    It is amazing how the ranking system changed but rules remained the same. I though you and Garry had changed a couple of rules But when I said I want to see full rules from both I meant ranking system incuded

    I distinguish in your posts an anxiety whether poeple will drop their games because of the rankings or lose their interest or fun because of them. Wow, I didn't know that the ratings had that power. People come here to play not to get rated. From my experience you have to ask a new player if he wants to be rated and not vice versa. Yes, sometimes people ask for it but most of them simply don't. And I am sure that even if they were not permitted to be rated they would surely stay afoot and continue playing their games with the same joy

    Now the rankings stand to rate people above all and the rest after. That is what its name defines, it's in the dictionary And you have the responsibility to ensure that people are equally and fairly rated. That's above all. The fun comes after. Because if the latter is your consern there are other ways to do that, more appropriate. What fun can I gain from poeple that can have unfairly high ranks even if I was one of them? I wonder... Either we make a ladder and rate people or make something else and have great fun.

    Now can you explain to me how the hell Lung is on top of a game but goes down because of it as you mentioned above? Do you mean that he goes up slower than he would normally go if his opponents were tougher? Or do you mean that he actually loses because his opponents are weak?

    For one thing I must admit that what I never liked in Quinns/Solver ranking system was the huge ups and downs But favoring people playing more games in both systems (?) might not be fair at all. Not sure if this is true, simply from what I read from your posts, but perhaps a formula that would give a slight advantage for been rated in many games but fading out as more games you add could be more fair, maybe not sure yet

    • Don't think the Quinns/Solver formulas favored many games too much, in fact, it didn't, unless you were very good in those games.

      Huge ups and downs? They were only a bit bigger than those of the Gavrushka/Blackice ratings, and actually you would rarely get or lose a point for one game.

        • Well, I have seen people dropping like 10-15 places (if I remember corectly) down. That's a huge down

          Anyway, I would like to add that I see a point in Pete's view but so do I in most of the rest views as well.

          We will have to step aside the temper postings and work together for better. I would suggest any interested spit out all his recommendations up to Saturday and then simulate how the ratings would work with each one of them. Then we can have a better view what can work and what can't work.

            To be honest when Garry and Pete took over the rankings Klair left the top of the ratings for good

              • OK, Pete, when I was talking about the "other ladder" I play on (in a different game), I was not referring to the "old" apolyton system, and by the sounds of it, it is quite different.

                This is the way it goes:

                Each pair of players in a game is considered a match. If the winner is ranked below the loser, then the winner moves half of the places toward the loser. The loser remains where they are. If the winner is ranked above the loser, there is no change in rankings. If the winner is ranked immediately below the loser, the two players swap ranks.

                Rankings are lowered by people in other games overtaking you.

                [B]Example:[B/]

                Rankings are:

                1st Player A
                2nd Player B
                3rd Player C
                4th Player D
                5th Player E
                6th Player F
                7th Player G
                8th Player H

                Let's say there's a x9th game where the positions are:

                Player F 1st
                Player C 2nd
                Player A 3rd
                Player G 4th

                Then Player F will move half way toward Player C, and halfway toward Player A, who are ranked above him/her. Similarly, C toward A (but not G, as that player is lower ranked), and A and G remain stationary, as A only defeated G, who is ranked lower, and G defeated noone.

                Hence the new rankings would be:

                1st Player A
                2nd Player B
                3rd Player C
                4th Player F
                5th Player D
                6th Player E
                7th Player G
                8th Player H

                (Note that F overtook C because of his/her victories, but then C overtook F because of his/her victories. Clear as mud, huh? )

                Although robust and popular, this form of ladder has some disadvantages, namely:

                - Players become interested in only playing against players ranked above them;
                - The higher up you are, the harder you are to overtake, for example No 1 rank may only be dislodged by a defeat by No 2 rank, and No 2 rank may only be dislodged by No 3 defeating No 2 or No 1, etc. This leads to high ranking players being selective about who they play based on rankings;
                - Cliques form, whereby players are given a leg-up up the ladder by their friends in higher ranks.

                It is for these reasons that I'm in favour of keeping the present system. However I have reservations, mainly due to this Lung phenomenon that keeps getting mentioned where he actually lost points by playing. After reading the formulae I can't understand how this would happen. Would someone please explain it to me?

                OK, now that I've achieved a half page post to compete with you guys I'm logging off to get back to reading books, playing golf and swimming in the balmy Philippines...

                • birdy a+c Rick that is how the old system worked. I totally agree with what you said. See people another one that thinks that style of rankings is bad news for gaming.

                  You can not have a Klair in the new rankings. The new rankings will not create an instant star because they are in many games. Keygen you and I have the only reality here. Many people in the old rankings dropped 10 to 15 positions in one 9th turn ranking. That was just plain unbalanced and received many complaints.

                  This is not chess btw tell me are chess games ranked every 9 turns of course not. The old system may work if the game was over and the game was ranked one time (like chess) but it isn't. You take massive dives and little gains per 9 turns with the old system.

                  Posted by Max Webster: One thing though about the ratings, shouldn't the number of games a person is involved with effect the person's standings? Is this possible or necessary? Just think its kind of weird with one person doing well in one game being at the top of the ratings.
                  Zobo's loss in ranking 6 to what 14, for what really one bad ranking in one game compared to what three good ranking games.

                  This happened and Zobo was not happy lost 8 positions for one loss and three wins fair I do not think so no one did.

                  Another example:
                  Teamhorses 4th place 04-28-2001

                  Starting points 21.723

                  BLACKICE 21.342
                  BLACKICE 20.966
                  BLACKICE 20.542
                  BLACKICE 20.679 down 1.044

                  High Voltage 1st place 04-25-2001

                  Starting points 21.364

                  BLACKICE 21.401
                  BLACKICE 21.630
                  BLACKICE 21.685
                  BLACKICE 21.723 up .359

                  Strife 1 st place 04-23-2001

                  Starting points 20.945

                  BLACKICE 20.945
                  BLACKICE 20.991
                  BLACKICE 21.094
                  BLACKICE 21.341
                  BLACKICE 21.364 up .419

                  Previous rating 008@ 20.995
                  Current rating 012@ 20.710


                  The Rating shown is the rating BEFORE adjustment. So your last
                  adjustment was with the 20.679 which then went to 20.710 upon defeating Darth Viper. Your rating didn't go up that much in your first two games because of the average lower level of players in those games. But your recent losses in Teamhorses set you back because you lost to lower rated players.


                  This extreme simply can not happen in the new system. You will not go down 4 positions in one 9th turn ranking. The fact you play lower ranked people is not as much of a factor either unless you are in first place over all. Two wins and one loss and you drop four positions not right is it. On top of that the old system does not promote play with lower ranked people. You would be silly to take that chance with these losses. The new system promotes play with lower ranked people unless like LUNG you are in first place. Had I continued to play based on the old system I would have been in 40th spot in the rankings in five 9th turn rankings. This is fair? this is balanced? I think not. Obviously this old system did not benefit good play. It penalized heavy for a single loss VS. Two wins. This can not happen in the new system it rewards for good play and can even reward for bad play (not often).
                  So by far a better system which pomotes games with all players

                  The current game Lung was in he put out the lions share of the pot. He makes little or negative gains he needed to be playing in other games with stronger opponents to make the posibility of gains again. he could not stay in only one game and expect to retain top spot either. Obviously Lung or anyone else for that matter will have to work extra hard to stay in first place. As it should be

                  • Blackice why don't you tell as rankings of your opponents at particular examples? If you have lose against much lower ranks you deserved to dive. It wouldn't happen against equal opponent. And your dive wouldn't drop to position 40, at 30 you would catch your ability and probably slowly start climbing.

                    It's said that because of personal frustrations whole system must be changed.

                      The opponents are quite not nessary to post the facts they are clear. Any opponent under you in the rankings the rule applies in my case 40 or more players. Again this goes back to another problem with the old system. This was already pointed out. Rick also makes his point clear. Because of the loss factor you would be dumb to play lessor ranked players wouldn't you? The old system promoted a situation where the top players were not very inclinded to play a lower ranked player.
                      The new system elliminates all that without I STRESS THIS AGAIN the need for new rules.

                      The win loss ratio is 2 to 1 (or more) in other words if you win two and lose once you lose points and drop big time in the rankings. What you are saying is that is fair and good? ok... Kralj I don't know if you noticed but no one is equal. They are either ahead of you or behind you...The dive would continue if the rankings stayed the same yes they would Kralj. Especially if you had a bad land game. Chances are most if not all players in the top 20 will be in new games with at least 3 players ranked well below you. Now you have bad land and a manditory ranking rule. Rather silly to play it...

                      CTP online gaming you get restarts on bad land to make the game fair and even. With the old system and manitory ranking you lose fairness all together that is simply wrong. You should be ranking skill not ranking starting position.

                      The system had to change because it was unfair and unbalanced that was (is) very clear to most.

                      • Okay. Thanks Birdman for stating how the old system works again. All the documentation on it, including examples, exists back in 2000-2001 Apolyton CTP posts. Maybe Solver can help with finding it if you all want to see it.

                        Why don't you all take a vote? That is the only fair way to resolve this. Some people like the old, some like the new. Why is this so heated? Just cast your vote and set a deadline. Once it is voted on, then you can decide on who and how to do the updates. Solver maybe can set up a "vote" here on Apolyton, where only the active PBEM players can vote.

                        Ice, it is not politics or bull****, it sounds like the people here just want a working system. I think that whatever system you all choose, in the end, someone must update it at least once a month in order to make it work.

                        • I have changed my mind. Blackice is right: CTP is not chess. Therefore, a special rating system must be developed to cater CTP's individual characteristics. Whether the Blackice/Gavrushka rating system thoroughly satisfies this purpose is yet to be proven. However, it is the only available system that deals with the majority of the issues that have been addressed in the past.

                            Still need the Gavrushka/Blackice formula in detail.

                            • me i'm afraid i will remain nuetral as i play for fun and i don't get why every 10 turns and not the whole game ? also i most often don't start takeing off on the PG till year 0 or later against AI. also didn't i read somewhere about a patch to make the AI stronger?

                              • I too play fer fun, for after reading how people look at other peoples turns and such, well, Ill just play fer fun.

                                I know all players dont, but me, well, I just like a good old fashioned fun-N-da-sun gameplay!

                                Now, I would like to vote, on the chance I change my mind and play, I like Pete's idea..I think he has a good head on his shoulders and he has helped me immensley with my playing ability and it has already reaped rewards, well, I been monitoring these posts and ya know, this is like a business meeting, "lets do this, lets form a committee to do this and report back" well, its been going on fer awhile now, no action, I would say this, not that i have any bearing on this matter, BUT I think the collective whole as a community should resolve this, by a vote, Name entered, not annonymous, and do so quickly, within a week or so, then get back to playing. All this talent here, a few too many insults and prima-donna's attitudes, but getting past that, without offending those whom are heading it up, I believe the players, whom are the core and have been through the good and bad oughta have the governing decisions to set parameters, and then finalize it (Solver, my suggestion this is where you move in and take the lead) and have a vote. Lets all help Solver generate this scoring system move forward, not sit and spin the wheels, I gotta be honest , all this talent and expertise, this should not be that big of a deal. As for heated discussions, well, thats part of the old human makeup, pride and determination!

                                Ok, please dont send me to Solver-Hall or Minapulco or chastise me fer my opinions, I am just an observer, trying to help!

                                I shall now sit down and let the gavel fall where it may!
