Believe it or not, there are some players with Glicko ratings so low, they don't have a 1.0 weight, even with the 0 cutoff. 0 is "roughly" unweighted, but maybe in the future I'll do *actually* unweighted. That being said, where do you see non-integers? Regarding the discrepancy between the usage stats and detailed stats, this is due to the fact that the usage stats remove all battles with less than six turns while the detailed stats do not. This is an oversight, and I'll correct it for the next month.
