[T206Collector]

Well, if T205 contained a 50-75% count of non-T206'ers, I think it would be almost obviously a supplemental set. Still, 1/6 of no overlap does suggest a sort of supplemental or update set. Whatever the reason, I do think the 32 players listed provide a key to understanding not only T205 distribution, but also T206 distribution. If I had the time, I'd research those players and write a thesis about it!
