I did not suggest that seeing gave validity... but it was most interesting
to see the difference in the picture that the two charts gave,
in the preconference there was a discussion from one of the cranial facial
teams on the difference in the plot using eigher the nchs vs the cdc charts..
the interesting thing is the curve difference with the same numbers... try it
and see..
