WEll the part of the code that determines body proportions is this
" [BODY_APPEARANCE_MODIFIER:HEIGHT:75:95:98:100:102:105:125]
[APP_MOD_IMPORTANCE:500]
[BODY_APPEARANCE_MODIFIER:BROADNESS:75:95:98:100:102:105:125]
[APP_MOD_IMPORTANCE:500]"
...snip...
These are percent modifiers to actual size based on a standard deviation bell curve... so its only saying the tallest human will be 25% taller than the average, and the shortest will be 25% shorter. There is nothing in the raws to actually determine the measured height or breadth of a given individual. As far as I can tell, there is not even any such thing as a measure of length defined anywhere in the game.
I could change those to have the center of the curve placed at any number I choose. The description page would list
[BODY_APPEARANCE_MODIFIER:BROADNESS:95:100:108:110:112:120:125]
Would make the average 110% of their given value. The tallest human here would still only be 25% larger, but the average would be 10% larger than the default value. Yes? In the description I would expect the actual average (110) to be listed as 'above' average.
With that in mind, I could make modifications to them population in general, as well as perhaps some creative management of relsizes?

Now if I could figure out how big the gobbos, dwarves, and elves 'should' be, and/or how they should vary. I want them more to balance each other out.
And to continue with implementing my own ideas of what the critters are.
