Quick Question about Poker Tracker....Just bought it, have 2500 hands (not alot) under my belt....

I have a question about the aggression factor rating. It says less than .70 = passive and greater than 1.5 = aggro.

I know 2500 hands isn't a lot, but I have been playing my normal game...and I have flop and turn aggro factors of 3.14 and 3.45 respectively and a river aggro factor of 4.39....

Is this a little too high? If 1.5 is aggressive, and I am 2-3x what qualifies as aggressive, could this be a leak? Or is poker tracker wrong with what it considers aggro?

I don't think I'm over-aggro, just playing my game...but looking at my stats tonight, I found that i was questioning that a bit.
