Is there any mention of transmit power control in the document? The fact
that some of the old limits are exactly half of they values you've given
makes me wonder if they weren't set lower for TPC, especially for
5250-5350 MHz where TPC is common.

Since you're changing these rules, I'd also like to see the frequency
ranges changed to match the documented ranges, i.e.:

  2400 - 2483.5
  5150 - 5250
  5250 - 5350
  5470 - 5710
  5735 - 5850

I left the gap in the 5470-5850 MHz range since I can't tell exactly
where the DFS requirement ends. Usually it seems to be 5725 MHz, but
that is not universal. If you can determine where the break is those
ranges could also be expanded.

Thanks,
Seth

from same document, just under the table for wifi range itself 5250∼5350
MHz and 5470∼5725 MHz need TPC and DFS

TPC rule is if power exceeds 25mW/MHz (this includes antenna gain), it
has do be able to reduce it under 12.5mW/Mhz.

DFS rule itself (DFS-JP) looks right.
