A read-only CwrFixedPointValue, in dBm, giving the average transmit power the subscriber unit used during the current operational minute, not a cumulative statistic. This gives a single representative power figure for the minute, smoothing out the momentary swings that the max and min pair alone would show. For example, an admin tracking p2mpSu1MinTxPowerAvg over many minutes could plot a trend line showing whether the unit's typical transmit power is steadily rising as conditions worsen over the course of a storm.
