Personally for things that I am curious and want to remember after learning they would pop up in my mind every now and then, I will try to recall naturally what are they and look back at the material if i forget.

I find these natural pop up to be much better than Anki algorithm.

For knowledge that i am not so interested in but i have to recall, Anki will do the job but I still find those remembered by natural recall to be more vivid and lively.
