I wonder if the program actually has something in it that would reduce the effectiveness of the kicker should a timeout be called just before the kick.
I also wonder -- in real life, it seems like the "iced kicker" never misses the FG -- I almost wonder if the "icing" actually helps the kicker by forcing him to take an extra minute to relax.
I also suspect that on those last second kicks, most kickers go out there expecting the "ice the kicker" routine -- if a team chose NOT to call the timeout, that might actually rattle the kicker.
