Rollout: 1st roll GS: 43: ?

After 11109, it's still TCTC. I would love to keep on rolling this out to significance, but a) not much would change, b) I have other rollouts to get to, and c) the logistics of my physical specifications prevent me from doing so. IOW, the computer needs to be unplugged. Unfortunately, this computer doesn't have fancy export to GOL HTML capability, which is apparently nowhere to be found in the latest gnubg. Weird.

It is likely that 24/21 24/20 is not correct by a small margin, and that 13/10 13/9 is not correct by a slightly larger margin. Interesting thing to note about this rollout is that two down was ahead for about 2000 games (because it lost the fewest gammons!), and at one point around 1296 games 24/21 13/9 was about 2 JSDs behind it. Anyway, between the splits, it's pretty close, with 24/21 13/9 ahead by ~0.9 JSDs.
