For what it's worth, my numbers are like (2500 NL50 FR hands only)

3.58 BB/Hand, 87% V$IP, 42% PFR 31% FIR... much noisier though. 22/33 are <1BB/hand and 44 is actually negative (never hit a set, lost $10 calling down a lag who had a hand).

Maybe it doesn't matter much how you play them... you win big when you hit sets, and maybe win/lose a little when you miss.
