The stat "VP$IP SB" has a Value Expression like this:
(cnt_vpip_sb / cnt_sb) * 100
We need to duplicate this stat (select it and click "Dup") and change the Value Expression to :
(cnt_vpip_bb / cnt_bb) * 100
However, before we can do that we need to create the new columns cnt_vpip_bb. cnt_bb already exists.
To do that select the existing column "cnt_vpip_sb" and click "Dup".
Change cnt_vpip_sb to:
cnt_vpip_bb =
sum( if[holdem_hand_player_statistics.flg_blind_
s = false AND holdem_hand_player_statistics.flg_blind_
b AND holdem_hand_player_statistics.flg_vpip, 1, 0] )
(i.e. just swap round the big and small blinds)
Now you can duplicate the stat and change it to use the new columns.
Remember to update the Format tab to reflect your changes.
