I think many learners are walking into a trap of thinking, if they just change their SPS algorithm, they will magically learn more. I think they might learn a little bit more, but the biggest effect is simply due to time investment and doing the repetitions. It is good to be able to practice known words less often, obviously, but that can be achieved using a very basic system already.

If changing their SPS or the promises about an SPS motivate the learner, then great, they're putting in the work and time to learn, but I doubt that the effect of changing the SPS is as large as some people claim.

For example I used a tool that supposedly uses FSPS, but it did have a low maximum for the duration you don't have to practice a word, and no way for me to "ban" a word, so that it asks me in 6 months or something, and simple words kept coming back, especially after not learning for a few days. I didn't make much progress using the tool, even though it had FSPS.
