What do you mean by the classical version of SuperMemo? Why not incremental reading?
I think a lot of the issues you mentioned are hinged on formulation which is a really hard skill and requires a lot of practice. Unfortunately I think anki is terrible for it because unlike SM it’s not that convenient (nor intended) for you to edit cards for applicability on each go.
Good point, SuperMemo is kind of made for you to make gradual adjustments to your flash cards, at least on the web site that is encouraged. Maybe you make a flash card in incremental reading, you don’t have to fix it right away, you can wait until the next review cycle to make a change.
