How SRS Works (video)
Just saw this great video on SRS (spaced repetition system/software), which provides an illuminating visual explanation:
> The video shows a grid of factoids, where new factoids are being presented at a constant rate. Over time, the factoids begin to fade to black… the closer they get to black, the closer they are to being forgotten. However, if they’re “recharged” by being relearned, they advance up a tier (represented by the color and number of the cell). The higher the tier, the longer it takes for the factoid to be forgotten. If at any point, a factoid gets completely forgotten, it is sent back down to the lowest level.
Be sure to click on “Show more” under the video to see the full explanation.
