You should consider to make leagues or do some swiss tourneys. What would happen, if you won't calculate all games between players which differ by more than 400 Elo? From the above ratings I can give you an example, why it does not work as it should, even with EloStat. I can see that Raffaela has a 30% score and a rating of 1951, (in reality it is hardly over 1500) imagine Raffaela had played 70x versus Fritz 8 and 30x against Kace (assume it wins all versus Kace(what I doubt) and loses all games versus Fritz8), it would get a highly inflated rating, which would influence also all other (in reality) weak opponents of Raffaela etc...
