If I can understand what you are asking for, and find a way to do it, sure,
but right now I don't have ha clue what you are talking about :-) You are
talking to a musician that know programming and math, but I don't know very
much about statistics, except simple terms like mean and median.
"Retention score" as I understand it, and as I (think) the "Retention
score" statistics tab works, is the percentage of cards asked that the user
recalled correctly. Is this right?
An example of how the Retention % would be used:

How would you calculate "Let's say, the Retention % for the sequence of
Intervals of 1day, 3 7 12"?
Then I'm lost with regards to what you want the plugin to do. Do you want
it to reschedule cards based on retention score? If so, this is more
complicated than I want to do at this time.
A little clueless, but still interested,
