I never did understand all that % body fat stuff as it applies to the weight spread limits. The % body fat criteria to me just applied to how they figured out how to determine the individual weight classes in a division.

Maybe it's just me and my math, but it just appears the weight spread limit numbers are a blanket number or rule of thumb rather than using actual percentages or real math. 15-20lb max rule might work decently for the 2-5lb weight group spreads in the lower weight groups in the kids divisions but when you start getting 10-20lb spreads in the actual weight classes then it sorta turns into a joke. Those 15-20lb max numbers would double or triple at the very least if you followed the math.

It would be interesting to find out where these numbers for max weight limit differences comes from and how it is formulated to apply arbitrarily to a division as a whole. As it stands it is limiting and ill applied.
