I agree with you 100%. It is close, I was thinking later that I autocall with QQ, autofold 88, anything between could go either way and I will do something different each time for no particular reason, instinct or whatever. And I don't know what M is nor do I care, perhaps I should but I think I'm doing Ok without it.

Results: I folded (this time). UTG called with AJ, pusher had 88. I was ahead and would have won as it turns out but I don't give a flip, I'm fine with my decision.

Thanks for the responses everyone.

Cheers.
