PT/Aggression Factor

[dancraw]

Let me start by saying I only have 6.5K hands in PT, so sample size is probably too small to ask questions about, but I'm going to anyway. I feel like I'm playing more aggressively than most of my opponents at 1/2, but my Aggression factor is at 1.26, which is way low I suspect. PF .64 F 2.46 T 2.39 R 1.42. Is that river number the problem? Is it just not betting enough hands for value on the end? Should I just shut up and not worry about it until I have more hands in PT?
