IMO, the only cure is the "Keep it simple, stupid" law.

For me, that comes down to the power/torque (at the wheels) under the curve. Everything else just further confuses the issue (and the conversation goes down 'the rabbit hole', but QUICK!).

The ONLY people engine dyno numbers are important to are (automotive) engineers and salesmen (bragging rights).

Case in point: When the Japanese got into the outboard motor competition, the domestic motors couldn't keep up with the Japanese outboards. The reason came down to the fact the Japanese rated their motors at the prop shaft, whereas domestic companies went for the crankshaft value.

Same with our cars: measurements at the wheels is what is really important. It doesn't matter how (power) got there, 'it is what it is and that's all that matters (or should matter).
