Screaming pitcher

[AtlUmpSteve]

Tom,

Using the range of 50mph to 60mph, can I also safely assume that, if the pitcher screams at the halfway point (0.20 to 0.25 seconds after actual release, and 0.20 to 0.25 seconds from ball to plate), and that the umpire (and batter) hear it (0.035 seconds later), that it is now already too late for it to be a distraction to the batter (since the ball will be in the catcher's mitt in 0.165 to 0.215 seconds)??
