aggression stats. what am i looking for?

[cdxx]

my aggro from the most recent session

i was wondering what people are looking in their own aggression stats. such as 0.8 pre-flop, 2.0 on the flop, then what?

over the last 1000 1/2 Party hands i've been tracking and trying to play more aggressive, currently standing at 0.8/1.7/2.5/2.0 AF, but this last session (100, mostly down but finished +4BB) surprised me.
