Bold Added.

Incorrect , absolute type of claim.

I've explained this error to you several times now.

That is your default assumption ... and I've explained to you several times the errors of making such an assumption ... especially without haveing sufficient data about the whole situation at hand.

I don't know about 'lord over'.

But I'll take evidence ... especially empirical evidence ... over opinion any day.

Your response so far to evidence that disagrees with your belief about the pusher and generator ... Disagrees with this claim you make about yourself.

You don't have to know or speculate ... I already explained it to you several times.

I've posted it before ... here it is again.

The summary of references and math previously shown in long posts ... lead to the easier to interrupt red and blue lines on the BSFC bellow... a BSFC that you picked.

Inside Red:
When the situation allows the pusher to dominantly operate it's ICE inside the red line area of the BSFC it is more efficient than the the generator.

Between Red and Blue:
When the situation and finite limits of the transmission force the pusher to dominantly operate its ICE outside the red ... but inside the blue ... has two options:
#1> Any Joules from the generator not cycled through the battery are more efficient from the generator than the pusher.

#2>Any Joules from the generator cycled through the battery are less efficient from the generator than the pusher.

Outside the Blue:
When the situation and finite limits of the transmission force the pusher to dominantly operate its ICE outside the blue ... the pusher is less efficient than the generator.
