When I was putting mine in, I just did a quick search on Google for the Avg. Body Fat % for High School Boys/Girls. It came up with a Range of 13-17% for Boys & 21-25% for Girls. My lightweights were at one end, middle in the middle & heavy's were at the top-end. I don't think it makes any difference in the long run, but I could be wrong. I think I put in a few different %'s, and the Minimum Weight Wrestled (MWW) didn't change.
