I kinda like the 35ft and 30ft rules for elders. It is still accommodating, but would stop healthy and strong 70 year olds from toeing the 30ft line, "just because they can." There would still be the medical exemption for anyone that could not pitch 40 or 35ft to move up. But they would have to prove it medically.
(I would suggest we get rid of the "Elders" division and have a Medically Exempt division instead. If you want to pitch 30ft because you cant make 40ft due to age induced issues, get a doctor's signature and move into that group. This would reinstate the intent behind the original rule).
I understand the youth top age. And looking at it from the perspective of the World Tournament, it seems to have reason as you have these 18 year olds at 80%+ clobbering 13 year olds. But that's the anomaly, which is one of the problems with NHPA rules, they are often based on the rare anomaly, not the norm; and often not with promotion in mind. When we get new kids out to pitch who are 15-18, most boys could pitch 40 ft distance, but none of them can do anything to control their shoe and never come back. Kids that same age can have better control and higher success (FUN) at 30ft. They learn the mechanics of the game and develop skill, instead of unloading the 40ft shoe with all their strength. We've had many broken backboards from a local high school that comes out and forces all the boys to pitch 40ft. Those boys don't want to be embarrassed for not making the distance, so they over compensate and let 'er rip with all their strength. We've never had a single kid in all the years that class has used our facility ever come out to a regular tournament, let alone express any interest in joining the NHPA.
Maybe your idea of the 35 distance would be good for Jr Boys the year before they age out. It would help start them moving back to the eventual 40ft, but it still allows some give in helping new kids learn the game in a more manageable fashion...a compromise.
Write them up and send them in.
