> Ok, so what you want to do is first cache the reviews and define our functions with this. Open up the console and paste it into there.

> localStorage.setItem('review_cache', JSON.stringify(dates));

> Then you can use the command `time_reviewed(longest_pause)`, where `longest_pause` is replaced with the longest pause (in minutes) between answers allowed. Anything longer than `longest_pause` will not count towards the total time reviewed.
> 
> You will be returned a number of hours and the number of sessions your choice of `longest_pause` results in. If the latter seems high, you might want to calibrate the former. How you interpret these is up to you.
