Slightly different here in the UK (You start at Cat 4, you get 12 points, you move up to cat 3 and NEVER move back down, 10 points for a local/regional race win, 1 point for 10th even if there are exactly 1010 riders)
I race cat 3 with an FTP at around 280-90. Realised a few years ago I could get up to cat 2 (40 pts) if I raced a lot, but I can’t race a lot. so that was that!
