Help me patch up my shorthanded 5/10 game: Starting Hands

[Bokonon]

I considered that, of course, as a big reason for the discrepancy. I'll have to check where I was playing the hands from, though -- I might play A7o UTG more, and maybe that's getting me into trouble. What I'd like to do is group hands in some reasonable way and then look at the stats for the combination (i.e., group A7o through A2o) and look at them as a whole -- the question is, besides the weak unsuited and suited aces, what kind of groups can I come up with?
