What we have is an interesting scenario (covering just a few players).
KoreanDJ can't be first because he lost to PC Chris.
Azen can't be first because he lost to Ken.
Ken can't be first because he lost to KoreanDJ.
ChuDat can't be first because he lost to Azen.
Ken has the advantage over Azen, ChuDat, and PC Chris but not KoreanDJ.
Azen has the advantage over ChuDat and KoreanDJ.
ChuDat has the advantage over KoreanDJ and PC Chris.
PC Chris has the advantage over KoreanDJ and Azen.
KoreanDJ has the advantage over Ken.
When I say advantage, I mean if they played a set, it's more than likely they would win based on past results (mostly).
If we removed KoreanDJ from the equation, Ken would be the most dominant player once again, but with KoreanDJ, what has happened to Ken is similar to what happened to PC Chris in Orlando and Chicago. Essentially, a lower seeded player (relatively speaking) has the number of a higher seeded player. Azen had PC Chris's number, so in Chicago and Orlando, where PC Chris would have later exits from the winner's/loser's bracket, he instead met an earlier than normal demise (basicly Azen took away his cushion).
The same bodes true for Ken, but to a more extragent extent regarding KoreanDJ, who sent him to an early exit in Orlando (where he then faced Isai). In New York, lets pretend the set against Azen was a mulligan, he ran into Mew2King in the losers, who he had been training with, and who had lost to KoreanDJ. In Vegas, he lost to KoreanDJ twice. KoreanDJ has been Ken's x-factor, but if you look at all the top players, Ken is the only one with just one real weakness, the rest are vulnerable to many other players, even ones I didn't mention.
KoreanDJ I think has the most potential out of anyone, so he may quickly rise to the top of the top.
