The stat “Bet when checked to” is very important to use in game. But I think currently it also includes those scenarios where the aggressor on previous street bets on the current street when checked to. For example, 1) Pre-flop raiser c-betting the flop when checked to, 2) Doble barreling on turn (in position after being checked to).
I think this dilutes the effectiveness of this stat. We already have a stat for C-bet IP% and Double Barrel IP%. Players generally look for “Bet when checked to” stat to figure out how often will the pre-flop caller bet on flop when the pre-flop raiser does not c-bet. Or how often will he bet the turn in position after calling the flop c-bet.
