z28, pretty much a sweet post except for your UTG preflop range. A 51/9 is not positionally aware and half the time that they raise preflop it's just garbage. Just taking the top 9% of their hands is a mistake. That's what makes preflop such an easy call.

This is probably correct. What's the "bottom edge" of a 9% preflop raise though? Something like KT? I think Pokey actually broke this down once before.
I just used pokerstove, and tried to pick the best 9% of hands - here's what I got as a range:
88-AA
AT-AKs
KQs/KQo = 9.2%
--------------
Here's what a 15% PFR might look like:
(same as above plus
All KJ, QJ, and JT combinations = 15.2%
Obviously, this doesn't mean that they won't occasionally raise hands like A9s or T9s, but it gives you an idea of roughly where the cutoff is.
