Add Anki SM-2 Algorithm to flashcard

First of all, thank you for making this feature.

But, The SM5 algorithm doesn’t seem right for me.

I choose Forgotten over and over with the same card, it’s odd that it’s scheduled 1 day back!
In anki and remnote, the same operation is scheduled 1 minute later.

Others must have thought the same.
Please review the algorithm for SM5 or consider adding the SM2 algorithm.
