Hi Hideki, No need to stop any of the weaker games since 99% of the compute time is consumed by the strongest half.
Also, only the new mogo's will be scheduled to play until they catch up - however their opponent will almost always be the stronger players. The probability of one of them playing against an opponent in the lower half is low. - Don Hideki Kato wrote: > Heikki, > > The numbers of games are about 200 and their ratings' standard > deviations (right of Elo) are 70 to 100, right now.
