Just to follow-up, I ran more experiments since writing the above
email and it didn't look like it was doing max() either -- at least
on my hardware/firmware combo it had no effect at all that I could tell.

I did verify that the wmi update went through to the firmware.

I can't remember now, but I may have been testing mesh mode in case
that makes a difference.
