[pbmserv-dev] ratings

["Benjamin Good" <good7972@hotmail.com>]

>>Maybe it would be possible to change the number of games after which a 
>>rating is established with regard to the game?  20 games of bg  or chess 
>>is easy, 20 games of dai shogi takes a few years. I guess anyone having 
>>played 10 games of dai or chu can safely be called established.

i'm not a statistics expert, or even particularly knowlegable, but i think 
the reason 20 games is used is because the way the ratings formula works, 
less than 20 games is not considered statistically meaningful.  but i could 
be wrong.  i'm sure if i am people will point this out.
