Aerohead did not imply that a 10% reduction in aero drag gives a 5% reduction in fuel consumption in all circumstances. He just refers to one specific case where the ratio was like that, without taking it any broader. If you think he did that's your warped vision of reality.

And it is like that every time. You seem hell bent on burning him into the ground.
When you believe you are in the right you give no quarter. This kills all meaningful conversation. That the accusations are often not or not fully justified makes it all the worse.

Then I find it hard to check your claims. You throw the book at it every time. Sorry but that does not cut it for me. Most people won't have the book or the time to delve into it. Should they then accept what you say without further explanation?
The real challenge is not to make claims, but to explain them in accessible terms. Which, I feel, Aerohead does way better than you do.

But the bickering, the insults! Why do you keep doing that? That conduct kills forums. It kills clubs, it kills choirs (my wife's choir just ended a month ago due to similar infighting), it ruins everything.
You have been banned temporarily here. You've been banned on InsightCentral for similar conduct.
Will you ever change before you are forced to leave?

Oh, I'm crazy and this is a happy forum full of misinformation. Now I'm convinced!
