PHEV real world gas mileage

I am having a problem with all the tests claiming that the PHEV will get a combined mpg figure of 25 with the battery depleted and 56 MPGe. First of all, why would you ever have a completely depleted battery short of a long highway trip with no braking? This does have regenerative braking, correct? My understanding is it will alway have 10% charge, even if it uses the gas engine to maintain that, so that you always have the full 323 hp when needed. So, with the battery always available like a normal hybrid, but not fully charged (and basically driving like an EV), what should the average combined mpg be? No way, should it be 25 mpg. If the Highlander with a 2.5 gas engine gets 35+ I would expect the CX90 to be closer to that figure. In normal mode, it should cycle between gas and EV mode like any hybrid since it is a normal hybrid, just with a much larger battery. Am I missing something? Maybe I don't fully understand what MPGe is? What I believe it is is an equivalent measure of how far a vehicle can travel on one gallon of gasoline. Which doesn't mean too much. Basically, with full charge, you get about 25 miles from battery plus 25 more miles with a gallon of gas so thats about 50. If MPGe really means the comparable mpg for a full tank than I would be happy with 56 but I don't think it does. Longer tests of the CX60 PHEV are usually claimng 35-45 mpg combined with daily charging. That makes sense compared to a Highlander since the CX90 doesn't have the soul crushing CVT and considerably more power. Am I missing something?
