For something that doesn’t run continuously, like eg. a refrigerator, then an average daily usage is more useful, no? “This product draws 1.5 kW with a duty cycle of 0.08” doesn’t really help when comparing efficiencies of potential purchases, you’d need to convert it to electricity consumed in a set period anyway.
Well yeah. You barely use groups on a personal machine - maybe once and done for audio and VMs, depending on what distro you use - and at work you’d automate that shit, probably have it centralised.
