Yes, that's the way it has been applied here. Match the zero point on the template with the point of highest roof camber, making adjustments as needed. It has had very good effect nearly all the time, on a variety of vehicles, in a variety of tests but usually testing has been limited to somewhat longterm fuel economy tracking. bobo333's pickup and lots of other pickups on EM have gained fuel economy applying the template to bed covers (sometimes really beautifully built too).

There was also a red Gen1 Insight with an excellent, beautiful red boattail. Yes, Julian, the template was used to improve the aero of YOUR car's already slippery body shape. Wanna do some throttle stop testing? THAT would be cool, given your fabrication abilities and testing opportunities.

There were kamm backs too that applied aspects of the template... you are swimming upstream here Julian in part because many of us have watched template ideas work nearly all the time when applied well. That has certainly been what I have seen these last 9 years.

EDIT: Here is MetroMPG's Insight build, a great thread with images, video, and test results (and a link to the red Insight):

SECOND AND LAST EDIT:

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
