That makes it possible to at least to some degree account for the noisy part. It's also a tradeoff between measuring in a realistic scenario which is close to normal use and a prepared setup which is aimed at getting more exact numbers. I think it would be interesting to do both and see what the numbers say. There certainly is a lot to be learned and to be improved here. For me the most important step is to be more aware of energy consumption and to try to get numbers at all. Any insight is welcome :-) -- Cornelius Schumacher
