I never bought into the lug-nuts (5, not center knockoff) coming loose.
The idea of a single knockoff coming loose I can see as it is spinning on the same axis as the wheel and I could see the inertia of the nut (especially with the wings) working it loose.
But a lug nut off center and with virtually no mass, I say show me the engineering report or the calculations, just not buying it. It being so negligible it was probably why it was ultimately dropped.
