OTOH, you are not controlling for a huge variable, namely opponent skill. Does FilthyRobot face the same set of opponents with enough frequency to use only those games?
Failing that, how about using only games where FilthyRobot wins by a certain VC, but then looking for a correlation between terrain and win time?
Controlling for opponent skill would be very difficult, almost impossible
One upside of the fact that he plays in a no-quitters group is that it tends to attract at least mostly serious players (people who have no experience aren't likely to commit to a 4-8 hour game). Also, there was a long stretch of time that encompasses a lot of games when he tended to be quite selective and mostly play with other very skilled players (like zempt, yoruus and purify).
So I don't think there is a vast range in opponent skill, but the variance is definitely there, and there isn't much we can do about it :-\
As for specific win conditions and times, it's a nice idea but sadly I don't think my dataset will be helpful. In multiplayer the "wins" are usually wrapped up by popular vote/consensus when a player has got so far. Nobody is going to wait for someone to take all the capitals. Occasionally there is a genuine space race and someone actually finished, but just as often there is a consensus "player X is an era ahead and just finished Apollo/got nukes, let's concede"
