hm..i looked around the forum and saw that similar doubts and questions already exists. that is possible with some sort of lets call it "cheating" play, for example, one day as tour master then second as a amateur then again as a tour master. or maybe i'm seeing it wrong, coz i looked at one player stats/score and things dont add up (at least for me)...i can post players name for someone more experienced to look it up for more explanations.
and ok, if a player enters a tourney with one rank and in that tourney he achieves other, then why is his score now with a higher tier in the same tier as amateurs? that's just dumb stupid. his results should be in a leader-boards with same level as his...in that way they are "stealing" prizes...anyway that should be fixed, thats all..
