Yes. And notice too that anything from 2-4* is really pretty close to the same thing. So a little imprecision will not make a major difference. And, anyway, no matter what we do not have the equipment for precision. And even then, we also have difficulty knowing how a diffuser interacts with other aero mods or features on our cars that make it different than the models on this graphic. So I say, try for three and get close and it will probably be good enough for a benefit. I am no expert. But that's how I understand what gets taught here.

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.
