I don't know about cyalexa's unit specifically, but power level 7 normally means that the unit runs at 7/10 of its maximum effect -- by either turning the actual microwaving on for 7/10 of the time then off for 3/10, or, if using "Inverter Technology" simply reducing the effective power level by 30%.
Yes, I know that and it still means nothing. 70% of "its maximum" rather depends on what its maximum might be.
That said, I'm not sure that 7 or 8 or 9 aren't random settings settled upon by the intern kid. I repeat, there is no standard.
Many years ago, I worked for a high-end hi-fi manufacturer. Someone (probably an accountant) decided that we should rate our award winning amplifier from 1-12 instead of 1-10. Sales increased and respectable reviewers praised our increased volume.
There was no increase.
These numbers are meaningless.
