Hello, so I’ve been using anki for a few years and I just downloaded the Anking MCAT deck about a week ago for MCAT studying. I never used FSRS before this deck but I enabled it after seeing the AnKing 2025 tutorial, and I set my desired retention to 90%. At first when I tried to optimize the parameters, I got “0 reviews” and that parameters were optimal, which makes sense to me since I hadn’t done any reviews for the deck yet.
Here’s where I think I maybe messed up. I optimized the parameters every other day (so I think 4 times in the first week) for that deck, which I now read that I should only be optimizing once a month. When I evaluated and checked the RMSE, it showed 23% which is absurdly high. I’m very new to FSRS and I still don’t quite understand a lot about it yet, so sorry if things I’ve done seem very obviously wrong but I’d appreciate any insight and what I should do next!
TLDR; optimized FSRS too often and RMSE is 23%.
