Are the multiple and frequent changes in power input  to a heat-pump considered to be detrimental to compressor  longevity????

I assume it is due to the control electronics trying to do it's thing in these shoulder months. I'm plotting it via a Shelly EM on the mains supply to a Daikin 6kw on pure weather compensation.
