What if..Burdick had classified T206's with respect to their individual 15 T-brands ?

As for as T215-1, I have not seen sufficient evidence that it belongs in T206. Off the top of my head I know, for example, that it contains only one Chase and no Evers but does contain the other 4 T206 super prints--thus has a "series fracture" that does not make total sense. T213-1 does contain all of the 6 T206 super prints, no "series fracture."

While "series fractionation" may be present, a "series fracture" excludes it--IMHO. I use the term "series fractionation" to simply mean a "series fracture" that makes sense--for example T213-1 includes 4 of the 14 T206 350 only Southern Leaguers, but these 4 are all of the Southern Association players of those 14. A "series fracture" in this example would be if T213-1 contained 2 of the 14, but there was no logic to deduce why?

Thus,

A "series fracture" is exclusionary, and "series fractionation" is not necessarily so.
