> Source: input 35 new vocab a day into Anki while learning Japanese a decade ago and grew my vocab deck to 18000+ cards. Reviews would take several hours a day, and at one point I stopped adding new words to try and wait for the daily review load to go down. When it never did despite this, I just deleted the entire thing and say fuck it. Yeah, but that isn't really inherent to the concept of SRS; it's just an unfortunate consequence of Anki's geriatric SRS algorithm. For reference, for my Japanese SRS app (which is using my own custom SRS algorithm) I have a user who currently maintains ~18k known words, with a consistent ~23 new cards per day for months, and they don't take that long with only something like ~20 minutes spent per day reviewing.
