@Great Butts lol - I'm excited to meet you as well!
I got both years from posts in page 3 of this thread - someone found the 2019 numbers on an archived site from the teaching hospital which had a breakdown and then someone else shared that their letter from last year (c/o 2020) referenced 1400 applicants total (no breakdown of IS/OOS). So the 2019 is "verified", but the 2020 is somewhat anecdotal. However, based on all the other calculations, I bet it's not far off from what we'll see when it's released.
