It's hard to say. I was under the impression that Panasonic was the only
company that used the inverter technology with actual percentages of power.
I dunno.

I can't vouch for current models but my Sharp has a "Power Level" button
and each press reduces the indicated power by 10%. When the oven is
running, there is a noticeable difference in sound from time to time and
the internal light also varies in intensity. The time for say 10% is not
accurately 10% of the total time but is close. For one minute at 10%,
the power apparently comes on twice.

Yes, that’s typical of how most microwaves achieve their various cooking
levels; e.g., 10%, 20%, 50%, etc. The magnetron tube is pulsed on and off
at full power at intervals that vary in accordance with the desired
percentage of power for cooking. This technology is as old as the very
first variable speed microwaves.

This site gives a very good explanation of how Panasonic’s inverter
technology works:
