A few things missing

There are many factors, some within and some outside a coaches control, that influence the use of pitch count.

Warm-Ups DO COUNT and should be considered. I coach in NY and the beginning of the season is pretty nippy, cold days tend to "stiffen" the pitcher's arm. Also, early in the season a pitcher's arm is not as developed or warmed-up as a pitcher's arm in the middle of the season.

Furthermore, keeping a pitch count is one thing while using it is completely different (see Little League World Series '98). I agree that pitch count is a figure that changes constantly depending on many things. This means coaches have to use common sense, which not all have. I develop my pitchers with an emphasis on arm strength. The first month it is rare for any of my pitchers to go more than 60 pitches in a game. However, by the last month the stronger, better conditioned, pitcher will be allowed to go a max of 110. Winning is not important enough for me to push a pitcher over the 110 mark.

This issue of common sense is also very important because kids do not have the understanding of injury and repurcussions for abuse of their body that adults have (or should have). A boy may tell you he feels fine, and he may. However, while his arm does not hurt at that moment, he is tearing it up and will feel it later. This is where the coach needs to realize his responsibility to protect and remove the pitcher before damage can be done.

Post pitching care is also important, I make my pitchers ice their arm after pitching, regardless if it hurts or not. The best way to fight an injury is never to get one.
