Scot - So let's focus then on just the quantity printed with Piedmont 350. I don't think this is a viable reason to categorize the cards into two groups.

The 14 subjects not printed with brown Hindu can be found about or slightly less than 2:1 to those that were.

In the Sovereign 460 subset at least 8 of the 46 group 4 (460 Only) subjects can be found in greater than 2:1 ratios to the others.

I don't think you would disagree that the Sovereign 460 subjects all belong in the same print group. So if the logic wouldn't apply to the Sovereign 460's, I don't believe it applies to the Piedmont southern league subjects.

We actually have seen these types of population variations in other back subsets. I can only speculate as to what in the printing process caused them.
