I'm not too worried, there's plenty of prior art. Besides, they
haven't sued me yet :-)

Looks like it. Is the patent approved? It can't be right because it's an
idea that has been around for very long.

REPETITION LEARNING SYSTEM AND METHOD"
> An adaptively-spaced repetition learning system and method facilitate
the learning of material over time through the presentation of the material
at ever-increasing intervals. Embodiments of the system and method present
a stimulus-response pair to a student to obtain a binary response that is
either correct or incorrect. The token is next presented to the student
based on the student's response. If the response is correct, then the token
is presented to the student based on the initial repetition interval
without modification. If the response is incorrect, then the learnedness
value is reset and the progression through the repetition intervals is
restarted. In some embodiments, the initial repetition intervals are
dynamically adjusted based on the student's response to obtain revised
repetition intervals. This is achieved by manipulating the exponent of the
mathematical term representing the curve of the repetition intervals.
