TRUST!!! just weigh-in friday night or sat. morning or move up a weight class. For those involved in pee-wee football. The kids have to weigh-in to see who can carry the ball and who can't. They don't have remote weigh-ins for that and everything seems to go just smooth.
It's the trust issue. I know when I wrestled in kids wrestling all those years ago. How coaches stood behind wrestlers with a clipboard and lifted them up to get the scale to break.
