Am I overplaying AK? PT stats

[SofaCoach]

Last weekend I was rereading Lee Jones' WLLHE and the section on AK got me thinking. He was commenting on how AK is a very strong hand preflop but often must be released early when the flop misses. This is a fairly obvious statement but it got me wondering if I do this effectively. I fear that I may stubbornly hang on to it too long. How can I tell? I could post and analyze numerous hands but I thought it may be more objective to post my PT stats for AK and get feedback from winning players who use PT.

I have about 70,000 hands in PT over the past year. That is a pittance for some here but it should be a sufficient sample size for analysis. AKo is my 5th most profitable hand, as it should be (behind AA, KK, QQ, and AKs). I have gotten AKo 662 times and am winning .61 BB/Hand with it. How does that compare with the winning players out there?

Here are the other pertinent stats (although BB/Hand is the key metric IMO)

PFR% 87.31
Win% 48.49
WtSD 52.57
W$SD 51.63
