There is no definition of 1step=0.5 dBm in mt7610 eeprom content. According to the feedback, when 1step = 1 dBm, the correct transmit power can be obtained.

At the very least, I recall power delta being 0.5db steps. I can't remember if there was a multiply or bit shift after that to normalise it though. However, since that also affects the value, you should probably double check that.

I'm not sure what's going on with 7610, but I think you ought to just log TX_ALC_CFG_0 writes on stock and mt76 just to make sure you don't accidentally do something potentially out of spec/regulations

Seems I misunderstood so it's time to close it.
