couple questions... when figuring the 'most recent 25% of rounds' getting double weighted...
1. If someone has 38 rounds to be calculated then 25% is 9.5... do you then use the most recent 10 or 9? (basically how is rounding done?)
2. I think I may have found a small flaw... when looking at the most recent rated rounds being doubled I would assume the last round of a tourney is more recent than the first right? I think the ratings are done so that the 1st round is seen as more recent than the 3rd which would slightly skew the ratings.
ie.
Date - Tourney - rnd# - rating
1/1 - TourneyA - rnd1 - 1005
1/1 - TourneyA - rnd2 - 965
1/1 - TourneyA - rnd3 - 990
1/1 - TourneyA - rnd4 - 925

if the double weighting dips into 1 round of this tourney then it should use the 925 or last round and I think (according to my math which may be flawed) its dipping into the 1st round. I've done the math for 4 people and if I use the most recent round (starting w/ the last rounds in a tourney) I get a # slightly diff. from their rating. If I use the 1st rounds of the tourney it matches your rating for them

(let me know if you need a little more explanation)

I'm not complaining since it appears to raise my rating ~5 pts and has lowered or raised others I've checked anywhere from 0 to 8pts!

Even though i'm ashamed of my crappy level of play as of late we can use my #s as an example if you want.
