Furthermore, you can see the exponential rise in retention with the number of times cards have been reviewed. After the first review, users typically have an average of just over 2 days of demonstrated retention, per cardParticularly careful readers may wonder how this is possible, given that we stated earlier that the first review interval is 5 days. The explanation is that we recently modified the review schedule so the first review is after 5 days. For most of Quantum Country's history the review schedule was more conservative, and this is the reason for the difference.. But by the sixth review that rises to an average of 54 days of demonstrated retention. That typically takes about 95 minutes of total review time to achieve. Given that the essay takes about 4 or so hours to read, this suggests that a less than 50% overhead in time commitment can provide many months or years of retention for almost all the important details in the essay.
