The key is to use programs for cooking rather than max power. The programs will use variable power levels to achieve more "even" cooking/reheating.

I read that the heat/cool heat/cool pattern of the 50% power level cooking for twice as long helps the heat to dissipate into the food, melt the ice crystals, and gives a better overall experience for taking 2x the time to cook the food.

I've not put that to the test myself with any scientific rigor but I have noticed better results with it personally.
