No, your data looks good. The first value is the system total, then each PW.
My smaller 2 powerwall system shows:
"nominal_full_pack_energy":27950
"nominal_full_pack_energy":13930
"nominal_full_pack_energy":14020
So similar results as yours. Installed in May 2018.
OK, so nearly zero degradation. Interesting.
I do have an "off normal" usage pattern. I work from home, so usually one or both cars are charging during the daytime, so the input to the 4 x PW2 system is attenuated (probably 5kw or less at a time, total) and much lower than if I was feeding in the full solar to them. This, in theory, should result in less heat generation and longer life.
