Are you willing to put your head on the chopping block for each and every A-B-A test that has ever been done by EM members ?
MetroMPG was quite obsessive about them
So we expect his results to be close to reality.
But was everybody else as committed ?
I ain't saying they cheated or something, but folks were regularly testing in conditions that varied beyond their control.
A couple degrees warmer or colder, would have meant a lot of difference to my V50 when it was right about its most sensitive temperature.
Extensive testing can take longer than it takes the sun to heat up the testing environment ...
Wind speed, wind direction are beyond one's control.
Even if there's hardly any wind, there's usually
some wind.
And it ain't always coming from the direction the weather guessers claim it will, nor is it always coming from the same direction.
But who's been testing with a wind meter giving both speed and direction ?
3% is hard to detect even in A-B-A testing
On my new car the smallest change on the display equals 4% ...
