This seems OK - you want something to start up from?
However, I don't think we do that in "normal" CQM, and building
different behaviour here seems a bit odd.

In particular, resetting it all the time seems even stranger, since
then you can only react at a granularity of these 4 frames. EWMA
catches fluctuations already, so I don't think you should do it this
way.
