Stick an old CD in the MW and you can see exactly when the RF power starts.

Good idea. Another way would be to cram a wad of paper between the
door and the oven, and use a microwave leakage detector to measure the
resultant leakage. It there's a slow rise in output, you'll see it on
the meter, which you won't see on the CD.
