I can't figure out how you would do that without bringing a tournament to a screeching halt. It would be time consuming even if everyone made weight. As I and some others were discussing the other night, we believe the best way to take weight cutting out of the equation is to do away with weight classes all together. Instead, have the weigh-ins on Friday evening and start grouping the kids from the lowest to the highest in a particular age group. No pre-designated groups and potentially you could see a new group of competitors every week.
The one problem with this idea is the host club would need an idea in advance of how many wrestlers from various clubs were going to be attending. So Acme Wrestling Club sends in a roster of an approximate number of kids from their club that will be attending along with the correct fees. Then at weigh-in on Friday evening each of those kids steps on the scales and at the completion of weigh-ins the computer bunches and then brackets them.
