I'm looking at an opponent who has an attempt to steal blinds number of 48.75 over a large sample. Yet when I look at position stats, the button VPIP is only 33 and the CO VPIP is only 20. RFI by position is 29 & 18, respectively. How could the attempt to steal number be so large in this case? How is it being calculated? Thanks.

It's the # of times a player raised from the CO, Button or Small Blind when everyone else folded before them and there were no other players prior to them having posted out of position.
