I agree that the T206:E93 (for example) ratio is more like 100:1 when you compare the total number of cards. My rough and ready 10:1 ratio is a "per subject" ratio; since there are 520+ subjects in the T206 set and only 30 in the E93 set, a 100:1 ratio in the total number of cards translates in to a much smaller ratio "per subject".
Josh,
I think I estimated that there are about 3,000-6,000 examples of a typical T206 subject extant. This was based on a rather convoluted analysis involving the fact that Demmitt (St. Louis) and O'Hara (St. Louis) are available only with Polar Bear and that about 6.6% of the 350-only subjects have the Polar Bear back. See the book for details.
