While we're talking about Microwave UX .. what is "High, Medium, Low"?? My current microwave is 1200W. My first was 800W.

A 1200W microwave should have settings 400, 600, 800, 1000, 1200 and an 800W microwave would be missing the 100W and 1200W settings.

That way, my mac-n-cheese would say "Cook on 1000W for 5 minutes" and it would work on EVERY microwave.

Magnetrons don't work that way sadly - you can't easily change their design power. This is why the microwave power setting is fractional time based.

Not the point, is it? 50 percent of a 1000W oven is basically 500W. W is energy / time, which is compatible with time division.

Which is why I didn't designate them as 600W, but just '600'. It's a standard which means your food will get hit with the equivalent of half the energy of your 1200W microwave. (Which, in most cases, is 50% on + 50% off. Which my current microwave calls "Medium" maybe?)
