Using the technically incorrect term "angular momentum" rather than the more correct term "moment of inertia" made me think the same thing. I would think a person tasked with building such a device would know their physics well enough to use the right term, but I may be wrong.

Maybe he is afraid of giving too much info away. By mentioning it, now the opposing side will be measuring angular momentum.

So now he needs to make a new test. Ow that that is out of the bag
