two pair win % stats over 30k hands @ $50NL 3 tabling @ UB

OK, just hit 30k hands and am starting to see the light of stastical significance. I did my 30k mile tuneup in poker tracker and found this in my final hand summaries:

1.) two pair make up 28% of my overall hands dealt

2.) my net Amount won was $2,172.20

3.) i had a total of 392 hands with two pair and won 298 of them, or 75.39%

Is that good enough? If I'm ending up with 2 pair 3/10 times, I better learn how to play those mamacitas pretty damn well. Jesus, this whole time I feel like I've been sweeping those fuckers under the rug.

Enlighten me
