Agression Frequency and auto-rate players

[smokylosecannon]

Hi, I am using new version of PokerAce HUD w/ Agression Frequency instead of Agression Factor. I think Agression Frequency better represent players agression. I have few questions though...

1) is there anyway to re-do auto-rate players using Agression Frequency instead of Agression Factor?

2) from your experience, what's the optimum range of Agression Frequency. I just want some guide line as to what's consider as agressive, passive, neutral...

thanks
