First of all, big kudos for not missing a single day. When I used flashcards in the past, missing even a couple of days led to an avalanche of cards to review.

Since you’ve been so consistent and are using your own software, have you experimented with different resurfacing rates? Did you notice a material difference in recall?

I have done a lot of algorithmic experiments. I wouldn't say I noticed a big difference in recall, but my graphs say that there definitely is one!

Is there a reason you chose to roll your own software instead of just using Anki? Custom algorithm you think is better than FSRS? UI preferences?
