this stat only has BU and CO? and not SB? i think i split the stat up correctly positionally and SB returns 0 while BU and CO add up the rest of the hands

it reads the column: cnt_steal_def_opp_bb which then reads the expression holdem_hand_player_statistics.flg_blind_def_opp

but attempt to steal the blinds stat uses combination of CO/BU/SB.

Do you mean "BB Faced Steal"?

This is just a pure count, and uses the column:
cnt_steal_def_opp_bb = sum( if[holdem_hand_player_statistics.flg_blind_def_opp AND holdem_hand_player_statistics.flg_blind_b, 1, 0])
..so doesn't depend on the steal raiser's position at all.
