I like the idea of using Bayesian ELO ratings instead. They should adapt better and faster. It would give better rank confidence than the current k factor. For example, kartofel would have kept a low confidence.

First, thank you very much, Don, for giving us a reliable 19x19 server.

Please consider increasing the time a program stays on the list until it ages off. I guess you drop programs from the ratings page after some time that depends on the number of games they have played. Since 19x19 games take 4 times longs, it seems you should allow four times as much time to age off the list, for the same number of games. I like seeing the top program's
results a little longer.

It would be nice if a program can get into position more quickly. Since the games take longer, it can take several days to climb up from the initial 1200 to 2000, especially if there is an early loos. Does it make sense to set the initial k value a little higher, or to set the initial rating to
1500 instead of 1200?
