I was mainly saying I don't understand why you were indicating we should presume or expect they would average out in an N=1 experiment. Even in much larger experiments that is not reliably the case. Science would be relatively easy if there were not a lot of noise in the real world. So, to be clear, my concern is mainly one of scale - the experiment is far too restricted to overlook this: the smaller the experiment, the more important this type of information. Perhaps you were not saying that such averaging might be possible in an N=1 experiment and I misread, since it seems that you comment here indicates a different point.

I of course agree that logging them is basic scientific methodology - in order to detect issues with the experiment, and even hopefully to see the signal through the noise.
