It does not matter if an IP is an advantage or disadvantage.
It does not matter if the pitcher really has not been called for illegal pitches before.
Pitches can be illegal, not the pitcher.
It does not matter if the coach complains.
It does not matter what we think about the coach.
It does not matter if the spectators complain or harass the umpires (might hurt recruiting though).
It does not matter if your partner agrees.
he call does not "give" the other team balls, bases or runs; the infraction does.
Lower levels or lower ages; I don't call it the first time, but stop the game, tell the coach what was illegal and let the coach correct or ignore it.
Ignoring it gets the next time called.
In spite of my comments, it is still a conundrum for me in a situation where the coach determines my rating.
A highlight for me is seeing a pitcher throw a legal warmup.
