they didn’t translate that to their lesson system. maybe out of fear of the autopilot mode they think is a thing. that has never been a problem for me though.
when i came back after 3 years and did my 1800er stack, i took a look at those 500 failed items, then looked again at the missed kanji. 60ish really were a problem, the rest were fine after i got reminded of them once, so i made a deck for them and drilled them.
when the 500 review follow-up came, i had no trouble anymore.
seriously, repetition is magic. it sure isn’t all there is to it, but it’s such an important part, it shouldn’t be left out.
now, i wish there was an automatic way to export a level to a spreadsheet or so, would save me an hour every level.
