We only started doing tournaments for the younger age groups recently. The older groups are working out well. The younger teams are where we see the biggest problems. There is a real need for pitching rules at those ages.
Our events alone are not enough. Many other organizations are getting involved. But it isn't easy and to do it right it adds expense. So, as ROOTHOG mentioned, many just can't do it right, even if they want to.
We are actually building a app to make everything much easier for us and the teams.
