setting SNGPT parameters

[bFunk]

I've been playing SNGs for a few years, first on Party Poker and now on Poker Stars and I'm finally going to purchase SNGPT.
I'm wondering if people have any guidelines for setting other people's calling ranges. Anybody have an idea what is the average calling range of Poker Stars players at different stack levels? Does SNGPT provide good guidelines for typical PokerStars players? Any suggestions from people who use SNGPT would be greatly appreciated.
I think I've been going overboard with pushing when my stack goes low. When I have 10x the big blind stack on the button or cutoff with 5-6 players, is it generally wrong to push with Ax? Kx?
