Aks vs. AKo

Question: my PT stats show that AKs is a big loser over a large number of hands (50k). Almost identical stats in the positive direction for AKo. For a while, I just chalked it up to variance. Then, I started playing AKs like it wasn't sooted. No matter what I do over the last 20k hands, AKs is a loser for me.

Is this a leak? How can I be playing the one so well and the other so badly with basically the same line used for each? Yes, I count the extra outs with the board flushes my direction, but I don't start shoving all-in or anything massively different from AKo.

I have looked at HH's, and AKs just seems to have been rivered by 3-outers a couple dozen times. In big pots, of course. I have cooled my c-betting on 9-high flops, pushed less hard with TPTK. I'm just lost here on a fix.

Any suggestions for how to proceed would be much appreciated. Probably a leak, but I don't know what to work on.

If AKo is a winner and you play it the same as AKs then it's just variance. Bare in mind that you get dealt AKs less than AKo.
