I just noticed that the → learning statistics seem to be erroneous. Here’s mine as of today:
The graph gives me a streak total of 362 with a best of 204 and a current streak of 18 days. While those numbers make absolutely no sense in themselves, the most notable thing is that I never missed out a single day in >3.5 years. But the stats tell me I missed my streak on 11/20/2020, 11/26/2020 and 4/7/2021. Also, the graph shows no learning events for tomorrow (04/30).
Also, the currently longest streak is this one with 1127 days:
This number used to show up in the stats, but not anymore (don’t know when this stopped, I rarely look at the stats).
As for a potential reason: in finished courses, I usually tend (after a while) to no longer complete a streak but rather only review the words up for review.
The question thus is: what serves as the basis for numbers in the stats?
While we’re at it: Memrise seems to send me a reminder on my (Android) phone only for the very last course I work on on any given day. Here, this is a course I finished eons ago but I do a longer session every Monday and usually on Tuesdays as well. When that happens (and I get a 1 day streak), Memrise will send me a streak-reminder. This reminder usually pops up after I worked through my list of courses (~20 presently). Can’t be right, huh?
