I still find it odd that the only two groups of people who seem to use the software a lot are med students and language learning enthusiasts.
Supermemo is really buggy, and the website is extremely disorganized, but has a lot of useful information on it. The main reason I use it is its incremental reading function. Essentially, you can import articles, and turn them into flashcards in one swoop, while still having access to the full text via built in search (if you choose).
For example, I just finished importing most of the CSS reference [1]. And it only took me ~10 minutes to open the tabs and import them into Supermemo. Each page will get whittled down into flashcards over the next few weeks.
As others have stated, my srs usage is actually quite a small portion of my day, and extremely high leverage.
The hardest skill to learn is learning how to make flashcards properly [2]. I almost exclusively rely on cloze deletions now.
I do my repetitions in the morning when my memory is still fresh.
