Personally, I've come around to believing you know a thing or two and I'm happy to have you post here. I just want you to take a chill pill beforehand.

It was a GM rule back in 1998 at 55 mph. It was then picked up and spread by Aerohead here as the title of the thread suggests: 10%=5%
It is one of the many rules of thumb that Aerohead has put up here that, I think, cause far more harm than good.
Rules of thumb are bad news in any car modification area - suspension, engine management - and aerodynamics.
