What is Calculating minisplit COP?
I live in north NH (zone 4a) and recently had a Mitsubishi MXZ-36NAHZ hyper heat pump with 5 ductless indoor units installed at/in my home.

The way I see it COP is only measurable under laboratory conditions. Much like the EPA milage estimates your real-world numbers have a ton of variables the lab is controlling and you are not so the numbers rarely match up.
Installing an oversized Muli split system tends result in an unhappy ownership experience.
