As long as you don't put it in the center, yes.
Even in center it will work given that the time you are heating isn't tiny.
The center is the least optimal place for even heating.
But nothing really lies in the center. If you put a pie dead center in the microwave, 99,99% of it wouldn't be in the center. Even the center of the turntable isn't in the center of the microwave.
You're missing the point.
The issue isn't just about the physical center of the plate or the microwave itself. The key point is how microwaves heat food unevenly. Microwaves create standing waves, which result in hot and cold spots. The center of the microwave tends to be one of the cold spots, regardless of where the turntable is.
When the plate rotates, the food gets exposed to more areas where microwaves are stronger, leading to more even heating. However, if you place something directly in the center, it's less likely to move through those stronger areas, which is why the center tends to be the least optimal spot for heating evenly.
It's not about whether 99% of the pie is centered—it's about how the energy is distributed within the microwave.
I know what you're trying to say but it just isn't that simple.
With my mother's 40 year old microwave the center is the worst spot but mine is just different. How the energy is distributed will differ from device to device.
You can't know where the standing waves occur so you'll just have to experiment but I'll agree that the safest guess is to put your food slightly off centered on the rotating disc.
No you're completely missing the point.
It's about how much of the volume the object can take up due to the plate spinning.
If it's perfectly centered, it only takes up its own volume. If it is off to the side it swoops around and takes up the volume that it takes up but on every quadrant of the plate as it rotates
I don't have any interest in discussing this with you any further
