No microwave is 80% efficient. The invertor might be, but the magnetron
isnt, and the oven as a whole isnt. Apart from invertor types, all are
50% efficient, but the newer IEC rating system makes it appear that
output powers and efficiency have gone up: they havent. Think of them
as like PMPO power ratings. The only significant advatnage of the
invertors is reduced weight.

Chaos defrost is just more marketing nonsense, its no better than
regularly cycled power.
