when i placed really bad at ss2 I only went down like 1/2 spots because as far as we can tell, that was just a bad day. but after this tourney, which shows consistently that there are at least 12 people better than me in our area, i was taken off completely.
Since we dont have a purely mathematical system for this PR, we can personally account for things like bad days, overly good days, missed tourneys,lucky brackets, and the like.
And since we only have tourneys like once every month to month and a half, it needs to be updated every tourney. because peoples skill levels can change a lot within the time between our tourneys. saying that they shouldnt be updated is like saying, that if a full months worth of hardcore trainging, wont make maverick better than artery clogger, or that i cant become better than tsai with 5 weeks of practice.
