understanding Channel-Width options and limitations due to country registrations plus interface vs CAPsMAN settings

No clue indeed. Or is it the second line that is added as extra, just to allow dfs on 5170-5250 limited to 20dBm???. Why would one do that, if it is available for 23 dBm without dfs?
Or is it to allow the DFS logic to jump to the non-DFS freq when radar is detected? Then indeed line 3 is redundant.

I will put it on top of my open ticket in regard to DFS and scan list + auto frequency - MikroTik

What do you think about my points 3.4 and 3.5?
