We never heard a confirmed number of POAU cases. I remember a number a bit less
than Roz does. I thought, it was anywhere between 2200 and 2500.
I agree with both of you, using this math:
Usually the total number of props or costumes or cels is 10-30% above the number
you would expect if every one were put in packs, where they plan for more to cover
damaged cards and replacements.
The sum of numbers of Hobby props is 7680, at 3:case = 2560 / 1.20 = 2133 cases
Total number of cels is 8100, at 3:case = 2700 / 1.20 = 2250 cases
Total number of Hobby costumes is 19,191, at 6:case = 3198 / 1.20 = 2665 cases
This hints that the "overage" was bigger for costumes, and there couldn't have been
more than 2560 Hobby cases if each one had 3 props. Probably the total was somewhere
in the 2250-2400 range. The 3 case toppers were reported somewhere as 900 each, and
that would fit the same overages as the cels.
But don't forget there were Retail cases too, with one costume per box. I don't
have notes saying how many boxes per case, but assuming 10:
Costume total = 5378 at 10:case = 538 / 1.20 = 448 Retail cases
So for Hobby and Retail combined, we're talking in the neighbourhood of 2700-2850 cases.
