3-year player seasons updated (Patreon)

For insiders or above, the historical player seasons are now updated through 2021. As mentioned in the last post, the old database has been split into a 1-year and 3-year table:

1-year (since 1955): https://backpicks.com/metrics/player-seasons/

3-year (since 1955): https://backpicks.com/metrics/3-year-player-seasons-since-1955/

I've also made a minor (Bayesian) update to the postseason stats, so you'll see slightly different numbers across the one-number metrics (BPM, AuPM) than you've seen in the last few years.
