That formula is only valid for pass grades, not fail grades. From the SM
website:
6. If the quality response was lower than 3 then start repetitions for the
item from the beginning without changing the E-Factor (i.e. use intervals
I(1), I(2) etc. as if the item was memorized anew).
But I agree that it's confusingly written.

For grades 2 and 3.

Because of lack of space, I abbreviated repetitions as reps. In Stats, reps
currently is learning reps + review reps, but I agree it's inconsistent with
the browser, so I've split this up by listing learning reps and review reps
separately in the statistics page too.

Scheduled interval is next rep - last rep. This indeed probably does not add
too much, so I've removed this from the statistics page.
Thanks for spotting this!
