I think I know what you are saying, but I do want to draw a line in the sand. P&G is what sets the bar when comparing efficiency, it is entirely well know here and here is where the discussion be. You cannot replace a driver/pilot with a computer and not account for what that driver/pilot can do with mere training.

You have to assume that there will be an optimum technique for operating this hybrid configuration as well, then match up all the speeds/parameters/efficiencies (including charge and discharge losses if it is actually an advantageous strategy) and figure out what a thinking pilot can do before and after. At least then you will know the upper limits on efficiency rather than starting from complete fudge.
