Pennsylvania TedI'm not sure I understand your math.
Also, there are 48 subjects in the 460-only Series....you have 55 ?
I prefer to use the "deduction method" to approach the # of possible EPDG cards......
524 - 6 (W P M D D O) - 48 (So Lgers) - 9 (150-only) = 461
Now, as we have found out with SOVEREIGN and POLAR BEAR studies....there are a good number
of these 461 possible cards that do not exist with an EPDG back. And, the only way that we can
arrive at the actual number is by large-sample surveys (i.e., Scot Reader's, Bill Brown's, and this
one)....that we are conducting here on this Forum.
