All we have is your pure speculation.

Deduction is not speculation. The whole point of engineering analysis is
to predict things you haven't tried by use of mathematical laws instead of
trial and error. I assert this cup of coffee will run downhill if I spill
it. That's speculation?

You have any references to back any of this up?

Early in this thread I cited the US CFR section that specifies the DOE
testing procedure (no doors, no contents, no icemaking). Physics and
thermodynamics are textbook subjects.
