This research cost question is driving me batty, so I've kept a pad by my computer and played a few quick games in the first century. One observation is that once RP's were accumulated towards a tech, I NEVER saw a recalculation of research cost until the next breakthrough. In other words, once I wrote down the research cost in the year of the breakthrough, I never had to scratch it out and change it.
I am quite positive, too, about the 1-2 RP's being gifted on some turns, and 1 RP being taken away on the breakthrough turn. Both these things happen about half the time, the rest of the time it works like it's supposed to. I don't think OCC games are a good comparison --the HQ base is always treated differently and I don't think these "oddities" arise from the HQ base.
It seems that research cost is calculated differently in multiplayer. I know I have seen research costs change in midstream in multiplayer, but I haven't observed it in SP since I started keeping records.
Also, I compared research costs from SP and MP games. Research costs are uniformly higher in MP for the same number of techs and same number of turns passed. For example, researching your 4th tech as Gaians in year 2113 on a huge map cost 45 RP in SP and 77 RP in MP. This is not due to a "being #1 in tech effect" because I was third place or worse in both cases (probably further behind in MP than in SP, if anything, which should have made the research cost less, not more).
Curiouser and curiouser!!
