Yes I have learned the exact same thing as you here. We use I was thought 30% for power 30% going into the cooling system, 30% use goes out the exhaust and the other 10% was figured in, in the weight of the car.
Kind of sucks that " Air Pumps " or engines are not that efficient, but there are ways that are making these a lot more effective and work better.
For example keeping the intake valve still open when the pistons starts to come back up, this reduces pumping loses. Also as I saw below in a post Direct injection is very helpful, instead of having the fuel + air in the intake manifold then coming in.
A great idea that companies do use, many do not though, I think Spark index is a great idea, and you would only really need it if you had the EFI we have today, direct injection would have to be set at t a angle to work correctly, but I have seen most come from the top and the spark plug is tilted in the chamber.
