and i went facking 0.12 down..i have a rate of 26..pro dizz a rate of 29
he went up +0.16 and i went down -0,12?? is this normal??? i have 3 rating points less..only 26 and i go down..so why does he increase rate soo much with a much higher rate of 29...
become this f|a server better rated?? or can someone explain pls??this is a little bit strange..cuz on this f|a server is kinda easy to do 20 ppm.
ps. nothing agains you pro*dizz if you read this..i just wonder...everyone goes up with 19 or 20 ppm on fa 2..on other server, players with less rating points loose rating by doing more ppm ...and average ppm and average rating on the map is almost same..

thx
sry for bad english
