To do this you will need to build a new column to count the number of times that your float bet won immediately, or how much money you won when you made a float bet.
You can do this in the same way that the built-in stat "Cbet Success Percentage" works.
To do this we need to take the column which counts the number of float bets ( let's use turn float as an example – cnt_t_float) and include checks for not seeing the river and not facing a raise, which means that the bet won immediately.
cnt_t_float =
sum(if[holdem_hand_player_statistics.flg_t_float, 1, 0])
So:
cnt_t_float_success =
sum(if[holdem_hand_player_statistics.flg_t_float
AND NOT(holdem_hand_player_statistics.flg_r_saw) AND NOT(holdem_hand_player_statistics.flg_r_face_raise), 1, 0])
Then you can build your "Turn Float Success" stat as:
(cnt_t_float_success / cnt_t_float) * 100
If you want to see how much money you won or lost in hands where you made a turn float then instead of counting the hands by counting 1 for each time you made a float bet you can count the amount of money you won in a new column, like this:
amt_won_t_float =
sum(if[holdem_hand_player_statistics.flg_t_float, holdem_hand_player_statistics.amt_won, 0])
..and then add a stat to display that.
