(hopefully) I also forgot one more important thing... blitz is one example of a really serious time problem. 5 0 highly favors computers. 2 12 is much better for humans that 5 0, yet both are blitz. I chose (a long time ago) to limit blitz to 5 3 or faster, and make everyone play longer time controls as "standard" to eliminate the time control problem... If you mix a bunch of 5 0 games, your rating will climb, then a bunch of 2 12 games will see it drop...
