T206 backs: can someone make a list

[tonyo]

My current t206 set building direction is to have a variety of backs that represent the ratio in which each back actually exists in the known t206 population.

Has anyone ever compiled a list of such ratios, or can that info be extracted from the excellent research that has been done by the back experts on this board?

I made my own attempt by using the info in Scot Readers "Inside t206" and the info in Bill Browns superset spreadsheet.

Not so sure I could recreate my methods exactly, but listed below is what I came up with:

The number shown before the back type is average number of each back needed in a 518 card set in order to represent the correct ratio.
