Never mind. To put it mildly, you've not shown yourself to be very open to new ideas, and that's OK.

(Not of course, that testing for changes in top speed to quantify drag changes is new!)
I believe that I do understand it, and that's why I'd never use it. You may believe that you're in command of knowledge you're not in possession of. A reflection of your comments.
When it comes to testing, there's nothing more important than BSFC. I don't believe you actually understand it. That's not a cut, just an observation.
Some SAE Papers supporting your method would be instructive.
