Cant be more ignorant than not counting at all.
True.
But I've yet to see a good argument for any specific number as a threshold. A lot of comparisons to baseball, but it's just nowhere near the same. I can easily throw 200 front toss pitches (full windmill, but not a full pitch with the lower body, etc) and not feel anything later. If I threw 200 overhand pitches I wouldn't be able to lift my arm over my head for a few days. You can absolutely overuse softball pitchers (and, btw, it doesn't always show up in arm fatigue/injuries as others have noted), but 100 softball pitches =/= 100 baseball pitches.
Pitch counts in softball could be a good thing. Copying baseball's pitch counts is pretty stupid and uninformed.
