This graph is taken from the article from Wired about Piotr Woźniak and his spaced repetition learning software SuperMemo: Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm

enter image description here

I would like to know how accurate this graph is:

  • Is the axes and the lines accurate?
  • When would the fifth reminder be?

    $\begingroup$ Hi, the graphs seems about right. This paper also using memory decay to optimize learning: onlinelibrary.wiley.com/doi/10.1111/tops.12183/… . Facts are not 'just' remembered after 60 days btw. The forgetting curve just keeps becoming less steep. I also believe that this is simply a graph to give you an idea of what is happening, and used simplified values. $\endgroup$ – Robin Kramer Jul 23 '16 at 13:16
