It has been my observation over the years most of the time if one kid has the other hoisted pretty high in the air, and there was a pretty loud thud when they hit the mat, and the kid being hoisted appeared to look hurt as a result, the call seems to be consistent with the old rule if it looks like a duck, sounds like a duck, and acts like a duck, it's probably a duck. I don't have any problem with that, problem are those few exceptions that are either called a slam for what most call a good boost, or worse, my pet peeve, not being called when it really needs to be. Some kids do need dialed back. I think we all know when a kid really meant to do it. Takes away from the sport.
