Dated Ratings

Paste a list of coach names (optional), select a country filter (optional), and enter a date range. If you leave coaches blank, we'll include all coaches. If you select a country, we'll only show coaches from that country. We start everyone at 150 on your chosen start date and recalculate ratings with the same BBANZ method, but without the extra "new player" boost. This runs in the background; you'll see an ETA and status.
