I looked this up again.

The idea was to support display of both instantaneous power and average power
if both is provided by the chip/driver.

With the above, this is displayed as follows: 

power: 55mW (avg: 50mW, highest: 70mW)

In other words, average power is displayed as limit, similar to lowest/highest values,
if instantaneous power is supported as well. If not, it is still displayed as before.

power: 50mW (highest: 70mW)

Do you have a better idea how to handle this case ?

Thanks,
Guenter
