Hmm, I have Anki and I don't see an option for this algorithm. Anyone know how to enable it? The preferences say I'm on the "V3 scheduler" but have no option for an algorithm. I don't think I'm on the algorithm described in the blog post because whenever I don't know a card it goes back to 1 day as if it was new. Or maybe I am on it and I'm just misunderstanding how this works? I'm on Mac, Version 2.1.66 (70506aeb).
Go into the deck preset options (any deck is fine). Look for the FSRS section and check if the toggle is enabled. If it's not there you probably are on an old version.

You're on an old version of Anki.
Once you upgrade, FSRS is available under the deck options.
