You may not be paying quite enough attention to position. I have 18/9 stats overall but my button stats are 27/12 and my utg stats are something like 11/6, and I think that's closer to ideal.

Incidentally, don't be scared of the £ tables. Is this Crypto? Because I play both (£ out of preference) and to be honest the difference in skill is less than the difference in value, if you see what I mean.
