Most of those speeds seem to be way too slow for high school. Our select teams for 13 yr old are 70 - 80. The 14/15 year olds are 75-84. The senior varsity players are 85-90+. I've clocked many of them myself with my Jugs.
P.S.
I suppose though if you averaged out all the total pitchers who can pitch on every team that the counts would go down.
