i think you can play more hands in position 4 for sure, maybe 3 also considering you expect by now to have an edge over your opponents.

My feeling is that there is little difference between UTG and UTG+! and the same can be said for MP1 and MP2 so id definitly play more hands in MP1.

7% UTG also suggests you are mucking 77/66. , id love to play 77 perhaps also 66, even if we only limped (allowing us to limp AA occasionally etc etc) Is it standard to muck these? have you results on that? or is it part of the 24 tabling that you have to give these up.

My results suggest that raising 77 UTG is def +ev 66 is meh ev depending on how i play it and <66 is def -ev
