"ped punt"??? ok - I'm from way south - is this an accepted technical term in Canada?

nevertheless - if you can get the measurements to use the formula from my training is:

Center of mass height = standing height - seated height (top of the head to the bottom or back of the thighs - essentially the seating surface, back straight, legs level) + elbow rest height (measurement in the seated position from the seating surface to the elbows).

Shortened: Cm = height - seated height + elbow rest height.

At 65 inches your female is near the 80th percentile for females -65.1 inches, the 80th percentile figures for the other measurements are 34.6 and 10.1 inches.

Cm = 65.1 - 34.6 + 10.1
= 40.6 inches

this is from a chart entitled "Basic U.S. Adult Consumer Anthropometric Reference", Canadians shouldn't be too different - the down side is that I have no cite as to the exact source.
