Thanks for the updates. I think there are some questions though be
answered in the documents you linked to. I find that tables like these
often have incomplete information. Sometimes they refer to other
documents, but I'm not seeing any such references here. I've tried to
find more complete documents, but I haven't had any luck.

Overall these look okay, but if you are able to find any additional
information to clarify some of these points it would be helpful.

It would be nice to know for sure, but without any additional
information keeping it at 20 dBm is the safe bet. Many countries do
require TPC in this range.

Here it would be nice to know if there are any additional restrictions
on use, e.g. TPC or DFS. That appears to be rare though, so it seems
unlikely.

That is generally the case for this range. What you suggest looks fine.

Probably not a typo, if 160 MHz channels are allowed the entry probably
just hasn't been updated. But those documents don't really state whether
or not they are allowed.

I don't it documenting any DFS requirement at all though, and severaly
entries in the db have a DFS requirement, so I'm not sure that really
clears up the question. I'm reading a translation of the document
though, so maybe I'm just not finding them.

Let me know if you're able to find any more information to clear up
these questions. Are you able to send the changes as a patch? If you
don't know how, that's fine, I can create a patch.

Thanks,
Seth
