I thought I was the only one that did any math on newer cards.
Every once in a while I'll try to figure out print runs where there are serial numbered cards and the odds on the wrapper so I can see how interesting the inserts without serial numbers are.
The Topps soccer cards surprise me, ending up at somewhere between 2000 and 4000 for each base card.
And some of the retail only inserts will be sleepers if it ever happens that anyone cares.
