That idea is definitely in the air, and for good reason. Anything (reasonable) we can do to prevent “overfitting” is probably worth considering. But here’s one thing that took me a long time to realize: instead of showing content in forms X and Y (chosen randomly), we can just have two different cards, one each for X and Y. That is, in a good system, it should be cheap enough to add cards that we can get some of the benefit of random variation just by having lots of somewhat different cards.
This is better for stuff like “someone famous is known by several names and we want to learn their year of birth” than for stuff like “I want to learn how to do simple integrals of a given form,” but it’s worth keeping in mind.
How many such cards do you usually make? In theory, there’s an infinite number of forms for card content Z. And I personally find it too costly (cognitive effort, time) during card creation to brainstorm the various ways in which I might encounter Z in the future.
I’ve recently been wondering whether introducing randomness to flashcard content might also improve… something

It depends a lot on the structure of what I’m trying to learn, but very often 2 to 5.
