Gilbert MainesIf you owned those three "substandard" but entirely legitimate cards, and they were important - would you be happy with the determination that they do not fit a mathematical model of the average card, and therefore you are sol?
Edited to add: I did not use those three cards in my computation of t/b variance.
Further edited - I also did not use the outliers at the other end of the size range.
I don't have a lot of t206s, so I really can not be sure what the typical border area of these cards is. But in looking at two, I see less than one eighth inch all around.
If the t/b variance is 1/8" then that variance has a tremendous potential for impact on any border area calculation. And although the side to side differences are less pronounced, they are still a significant percentage of the potential total area.
So, I am unsure of this approach for application to cards which exhibit as high a border area difference between cards as has been shown for this set.
