How to best rush production

[the_rest]

Hey guys, it recently occured to me that people dont rush properly the production at a base. So here is how i rush things.

Now the problem is that if you just rush it with the money the computer asks, you will build the thing in zero turns. But zero turns is just as 1 turns to complete ... And there is still another thingie to consider: if your base produces more then 10 minerals, all the minerals above 10 minerals is wasted! (you can get only the first 10 minerals at the new turn, not more).

So how do you rush it to be just 1 turn and NOT WASTE more credits then necesary ? Well here it is the formula, it works only if you have build for 10 or more minerals already:
1. remember the credits the computer says are needed
2. remeber the total minerals the base produces, and double that number
3. substract from no1 the no2. You can manually rush by that.

Now you will complete whatever you build in 1 turn exactly, no credits no minerals wasted. This doesnt work if you didnt already build the first 10 minerals! (in other words, doesnt work if rush price is double)

now here is an example with the saved file:
Zakharov of the University, 2103a.zip
so you want to rush the formers at University Base.
step1: computer asks for 19 credits.
step2: University Base produces 2 minerals, double that
step3: 19credits-4=15credits needed to complete the formers in 1 turn.
however you dont have enough credits! but if you complete 1 turn, here is what you get:
step1: computer asks for 13 credits
step2: mineral output is 2 minerals, double that
step3: 13credits-4=9credits. so if you rush formers production by 9 credits, it will just be enough to complete the formers in 1 exactly turn.

A neat tip. Thank you

Whoops - put this in the wrong thread.

Your formula is useful approximation (easy to calculate) but it is not correct. The actual formula for partial rush buys is as follows:

Let M be the total number of minerals needed for completion, P the production of your base and C the total rush buy cost. Then the partial rush buy cost Cp is

Cp = RoundUp(C*(M-P)/M)


1st Example:
You found a new base (2 production/turn) and immediatly rush a former. Rush cost is 25 Ec for 10 Minerals. You can buy the needed 8 minerals with

Cp = RoundUp(25*(10-2)/10) = 20 Ec .

2nd Example:
You are under attack and want to rush an expensive defender (1-5-1*2, Flak, Trained) for 50 minerals. The base has 10 minerals accumulated and produces another 10 next turn. Total rush buy cost is 160 Ec for 40 minerals.

Cp = RoundUp(160*(40-10)/40) = 120

In this case your approximate formula would overpay by alot.
