Poker Stars PF all-ins %

[youwereborn]

I play alot on pokerstars and people are always saying there are to many suck outs. (For example, AJo vs A6o is about 27% to 73% but it seems on PS its about 40% to 60%) At first I thought a site that big would be accurate. The more I play, however, the more I think the odds are skewed. Im not just saying this out of frustration or anything, I have really thought about this logically and it seems there may be a curve. Has anyone ever done any studies about this? Has anyone ever written down several all ins and kept records of the winners? Am I crazy?
