Why not use the average weight of Olympic Athletes in that age range.
Now, do we use the East German Woman's swimming team, or the Chineese woman's gymnastic team?
;^)
did you know that the East German state does not exist since 1990? Hope your charts in the plane are updated
hahahah, I wanted to post the same thing.
I say set a maximum weight, and no minimum. Get some people willing to really push the limits of the human body if they want to compete. Set the max combined crew weight at something like 165 lbs.
