I used the following filter to look at some of my last month's stats:
Position: Cutoff and button.
PF action facing player: Unopened.
There's total of 2626 hands when I used the above filters. I applied more filter by preflop actions and here's the numbers I get:
Fold: 1552 hands, Raise: 974 hands, Check: 1 hand. So there's 99 hands missing? What am I missing here?
