I feel like from a habit-forming perspective Anki would benefit from a fixed-time mode instead of varying the number of reviews. The default daily maximum is 200 reviews per deck, I think, but it's hard to tell whether that's too little or way too much until you've hit that level.

If you could set a study time of say 30 minutes, then when you skip a day, you could just do your usual 30 minutes and maybe only get through 50% of the scheduled cards, but you could slowly catch up over the next few days. And if on the contrary you run out of reviews for today, you could carry on with some scheduled for tomorrow until you've hit your target time.

FSRS can handle off-schedule reviews just fine, I think, so it should be able to accommodate such a rhythm where you don't always review cards on exactly the optimal day.
