The GP was talking in relation to W/Kg, and the output per Kg is definitely not e=mc^2. It helps reading things in the context.

You are correct, though it would help to clarify that you're correcting the GP on the "per kilo" part, and not the "energy" part.

I agree, if you're deploying 1 kg of fissile material, only 0.1% of that will be converted to energy. We should talk about energy per mass of fissile material, not energy per mass of "mass difference".
