Love the Wakitani SRS! Yet, due to the simplicity of the algorithm (and my erratic performance) the number of reviews per day varies greatly from day to day.
It would be helpful if the reviews were load balanced, by delaying some non-critical reviews by 1 or 2 days (which shouldn’t effect memory).
Of course, I naturally do more lessons on days with less reviews, thus creating more review imbalances later.
Also if I have a great day, and catch up on missed reviews, this creates a wave of high-review days behind it (at SRS intervals). This is why binging my reviews always bites me later.
