Another thing that you have to remember as far as broken targets go- (and I am saying this from experience, because we just had a four day trap shoot at my club and I was one of the reloaders who reloaded the traps) broken targets won't usually be broken when they are thrown unless they are broken when they are loaded into the thrower. I loaded two traps for four days and we never had any broken targets....... I also load our skeet houses all of the time and we don't get that many broken targets unless someone has handled them badly before they are loaded. So, unless your machines are really messed up, they should not be breaking targets when they are thrown. Except maybe ocassionally.
