Yeah, I fully agree that in general, we need to integrate explanations of "why is this task optimal for my learning" into the product. It's definitely on the roadmap, but it's a challenging because there's too much info to simply tell a student everything up-front. We have to do it just-in-time. But I'm glad that you were able to find a Reddit post of mine that answered your question. It'll be some time before we have all this info properly integrated into the product itself, but for now, if you're interested in reading more about why the system works the way it does, I'd recommend checking out my working draft of The Math Academy Way (https://www.justinmath.com/books/#the-math-academy-way).

I'm glad that you're having a good experience with the quizzes! That's exactly what we aim for: frequent, low-stakes, broad-coverage quizzes that challenge you to show off what you've learned (instead of stressing you out and overwhelming you). Used properly like this, quizzes are an extremely powerful learning tool. You get the benefits of retrieval practice, the spacing effect, and interleaving, all merged into one. And we pinpoint exactly what skills you need more practice on (which we have you review immediately afterwards), and by carefully calibrating the time constraint, we make sure you're developing your skills fully to the point of automaticity.
