I would like to switch to FSRS but I have a lot of manual reviews that can’t be taken into account and may cause the scheduling to be way off.
These reviews show in the card history as “manual”, with a rating of 0.
I’m thinking there must be something I can do with the DB to change the type from manual to review and change the rating from 0 to 2, 3 or 4 depending on how the interval changed (so 2 if the interval went down, 3 if it went up by a factor of 2 or less, 4 if it went up by more than that).
Anyone know if that can be done in DB Browser?
Also, does Anki store the flag history for cards anywhere?
