GBDP's

anyone know of any charts or spread sheet that has calculated GB A's on players cards.

Best that I know: the Diamond Dope individual reader card. But it's a long process.

Also, all non-Cadillac cards (the Chevy cards, is that how we call them?) have 20 gbA. That goes with years, like all 1925 cards have 20 gbA whereas in Cadillac years, like 1927 if I recall correctly, gbA varies from one player to another.
