On NEEPs heat pump performance spreadsheet (https://neep.org/node/3725/download/b8d1bfe31bf9ce47b653aca123c6feeb), amongst the wealth of data, it gives Min/Rated/Max for Capacity/Input (kW)/COP at 47°F/17°F/5°F.

I’m in 4C, quite moderate, with a 99% temp of low 20s and the lowest temp (in 20 years) of about 8°F.

Looking at all the performance data, am I right in saying that my priorities should be the
1. Minimum capacity and its COP at 47°F (many winter days in the 40s)
2. Rated capacity and its COP at 17°F (looking for a respectable COP @ Manual J calculated load) AND
3. Max capacity at 5°F (to ensure adequate capacity at 1% temp at ANY COP)

Using the Fujitsu 09RLF as the gold standard, it modulates down to 3,100 btu @47°F with a COP of 6.0.
At several degrees below my design temp it’s rated for 9,400btu @17°F with a COP of 2.88 (and still has a good COP at a higher capacity). By extrapolation, at my design temp, it will be modulating and run a COP better than 2.88.
During the Polar Vortex hours, it still has plenty of capacity.

Is that the right reading of it all?
