Did you feel the age categories we chose (0-3, 4-7, 8-11, 12-14, 15-18) appropriately capture stages of development,
Due to the rapid morphing of children over a given time, I feel it should be broken down even further. Also puberty sets in at different ages, so other factors can also be taken into consideration.

Age preference
A. 0-1 yrs
B. 2-3 yrs
C. 4-5 yrs
D. 6-7 yrs
E. 8-9 yrs
F. 10-11 yrs
G. 12-13 yrs
H. 14-15 yrs
I. 15-17 yrs

development preference
J. no pubic hair
K. slight pubic hair
L. some pubic hair
M. full pubic hair
N. shaved
O. flat chest, immature nipples
P. flat chest, maturing nipples
Q. small developing breast
R. larger breasts

body type
S. thin
T. medium
U. shapely
V. overweight

Using these parameters, I would be a D, E, F, J, K, O, P, S, T, U.
Just my two cents.
