My very simple microwaving trick esp if you don't know the settings (meeeee), whatever the basic option is, turn that on for 20 secs first, for eggs, then you check the doneness and also shake shake a bit. Then nuke it for another 20 secs. Another way to decide how done you want is to track the pops. Watery stuff like eggs will have uneven pops but that does tell you parts of it is pretty much cooked. I usually pause and shake after the first couple of pops.

Yes, very science.
