Microwave Power settings

Why is microwaving at full power for half the time, not the same as microwaving at half-power for twice the time. What's happening that's beneficial when the pulse is off half the time?
Best Answer
A microwave heats pretty unevenly — most of the heating goes into the outmost portion of the food, and even that isn't always even (e.g., bottom probably gets fairly little). That's not unique to a microwave; a pan mainly heats the bottom; an oven...
Mostly, the lower power settings give more time for the heat to even out by inside the food. Depending on the food, you could run at a higher power setting and keep pulling it out to stir, rotate, etc. Often quicker, but much more work.

How do I know the power level of my microwave?
It's usually on a label right on the door or inside it. And if all else fails, it's easy to test wattage on your own. Wattage ranges from 600 to 1,200 and is a pretty good indicator of a microwave's power (the higher the wattage, the more powerful it is).Microwave Power Setting Explained

far from an expert, but my guess it´s because the food continues cooking while the microwave is off...it is similar to leaving a dish unopened for a while after cooking...
if I had to guestimate, I would use 75% continuous cooking time to approximate a 50% intermittent time
