So why do we need to split out > 5210-5230 separate from 5150-5210? I did some tests with regdb and I found out that the rule to be applied depends on the main 20 MHz channel. With the rules above, if I select channel 48 (5230-5250) and enable VHT40, then the TX power is set to 17 dBm. OTOH if I select channel 44 (5210–5230) and enable VHT40, then the TX power is set to 20 dBm. I'm not sure whether my result is really correct, though.
