don't a lot of players get signals from their own teammate if he is on base and can see the catcher's signal? i remember a few years ago tony gwynn was accused of often getting tipped off by a teammate. of course tony was only being tipped of a small percentage of the time.


but if you had access to video you could probably calculate tony's ave with and without tips and that would give you a pretty good estimate in regards to how it would affect a player.


intuitively, i would guess that in the OP's scenerio it would raise a players batting average as much as .075 though it might be more appropriate to express the change as a percentage gain. its likely it would help good batters more than bad batters.
