Hi Sean - this implementation is Leitner, which would be ok for my needs, 
although I don’t quite know how you choose or specify the probabilities that 
are needed for this particularly implementation (and Leitner descriptions don’t 
mention this, but I can see the intent is to give you a random flashcard 
favouring new or unlearned cards and occasionally giving a learned card - but 
I’m not quite sure how you decide what to specify for that… I’m enquiring.

SM-2 always intrigued me… and would be cool to plug that in and compare - but 
was trying to avoid the inevitable rabbit hole and not get the actual task done 
(Which it sounds like you thought too…)
