3) It's impossible to contradict an ' assertion' when no one is in possession of the facts which would prove the correctness about how a Tesla Model 3 'might' perform at lower mass. It's pure speculation.

This, exactly (emphasis added):

This is
exactly what the paper shows, in these two charts which I posted previously:
Even though BTW efficiency is slightly lower for the lighter EV,
its overall efficiency measured in Wh/kilometer is better than the heavier EV.
As I pointed out before, you seem to be confusing the definition of "efficiency" in the paper (percentage of stored energy that makes it to the wheels) and "efficiency" meaning the amount of energy required to travel a given distance.
