There are lots of variables in numbers like this
You'd have to break it down by like, the TYPE of pitcher that has to do multiple disengagements, the type of runner that will only chance it with an 11 foot lead, etc.
Like, in the third bucket you could have slower runners choosing to attempt steals more often because they get a bigger lead. You also might only see pitchers in that bucket who have worse pickoff moves (guys with elite moves don't really need to do repeated disengagements...)
