Just purchased PT.... am I a NIT?

[Northern]

I am a first time poster so bare with me, and I apologize for the length. I am not new to playing online but after being stacked too many times by NITS or laying down a monster against a LAG so I decided PT would be a good investment and so I could attempt to track all stats.

After 9500 hands my VP$IP is 16.43, PFR% is 7.85 and PFAF is .84 and I have been winning at 5.5bb/100.

Judging from those stats I look like a NIT but my issue is I 6-table and often 8-table. So when multitabling I would normally play fewer hands and concentrate more on position, could that be reason for my stats?

Also from my small database the average players stats are VP$IP of 25.52 and a PFR% 6.79 and the biggest winners are close to my stats with <25 VP$IP.

Do these stats hold up over a larger database or is it just due to my smaller collectino of hands?
