First, Road and Track is not a Scientific publication. The consensus here is to support claims with
multiple citations of tests with Scientific merit, or to conduct one's own tests using proper technique.
Mr. DAN, I believe you are on a slippery slope with such speculation.
Please respond to this thread to confirm or deny these claims.
On the issue of testing, the best instrumentation we have (available in mass), is the ScanGauge. True, it is not perfect; however, by using the instrument in simple tests, it is entirely possible to isolate a variable to gather data, and publish the experiment for others to attempt.
As a reminder to all who have forgotten or are not aware, please see this quick definition of the
"Scientific Method".
