I tend to agree with you Larry on both counts.

But if one adopts the limited definition of a variation as a card intentionally changed by the manufacturer are double prints in a set, like the 52 Mantle, Thompson and Robinson variations ( or the many checklist DPs of the 60s and 70s) ? The differences were not specifically intentional but did result from intentional decisions in the set up of the sheet.

Are the 62 greenies that did not involve pose differences variations ?

How about the 82 Blackless "set " They are just unintentional print defects but ended up in packs. Variations ? SCD listed them as a separate set

I tend to view DP differences as variations. The greenies also. But I tend to view the 82 Blackless as print defects, although clearly they are recognized by the hobby as either variations or a separate subset of the 82 Topps.

Also agree that each collector should make their own call
