well to be honest with you no matter how many games they play, there will be a
margin of error,the real margin of error might actually increase after a certain
number of games on swedish list .the main use on the swedish list is how strong
a computer is against another computer .
one of the things that i always wonder about is how all the ratings of
older chess computers keep dropping until they eventually drop off the list. now
i know the old computers are not getting old age or bad health.the computers
play the exact strenth as the day they were created,the swedish system is flawed
in this respect . but it is the best thing out there for figure out which NEW
program is best.
