Given users were self-selected SuperMemo users who needed to use GitHub to upload exported stats, it feels a low (FSRS benchmarks average ~70k per user, filtered to a random selection of users with > 10k reps).

I wasn't involved in the benchmark, and don't know whether `SM16-v-SM17.csv` is a full export. Didn't see any reviews before 2020, and it may only be an export of a subset of reviews.
