Eric BrehmDave H. -- SGC does distinguish T206's by back type (on the slabs and in their pop reports), and as far as I know they have always done it that way. Their pop reports also show the totals in each grade across all back types, which is useful for those who don't care about backs.
PSA only recently started doing holdering by back type, and now they have a mess, at least as far as pop reports go, because of the mixture of the two different schemes in use at different times. Maybe they should adopt a hierarchical pop report scheme, like SGC uses, that allows you to see the totals for all backs as well as the individual back stats. For PSA this would still be confusing, since the back stats wouldn't sum to the totals (i.e. the totals would still include the old generic back data), but it would be better than what they have now.
