ATo is making me sick.

Hello. I've been reading the forums for about a month now. I was wondering if anyone could elaborate on why A10o is consistantly at the bottom of my poker tracker list when it comes to the Net loss I have on the hand. I keep a different database for the 6 sites I play on. About 30k hands total and A10o is always near the bottom!

The hand treats me so bad that I've made it habbit to only limp in in late postion with it. Is this making things worse?
