CGOS tracks the ratings as floating point numbers but rounds the results for display. If you see two identical ratings on CGOS, the one listed on top is the higher rating, even if only by a tiny fraction. But even if they were integers, it would make little difference since ELO is self balancing. If a few wins failed to give you the credit you deserve due to roundoff, then you become slightly under-rated, which causes further wins to count more, and further losses to have less impact. It would be very difficult to get off by more than a very few ELO points due to round-off error. In clubs, they often rate with a rating chart, that is integer based and this is perfectly adequate. - Don > Cheers, > David > > > > _______________________________________________ > computer-go mailing list > [email protected] > http://www.computer-go.org/mailman/listinfo/computer-go/ _______________________________________________ computer-go mailing list [email protected] http://www.computer-go.org/mailman/listinfo/computer-go/
