Well we are definitely comparing our readings of the tea leaves here, so... You point out that "Honda did a good job," and I'd agree. The tufts surprised me and then discussing it here, looking closely again at the rear window angle, and reading in Hucho demonstrated that my coupe has an approximation of the 22 or 23 angle Hucho's description suggest is often highly effective for the notchbacks. That and a ton of other optimization.

I think that your Legend shows a similar pattern. Look at how the top tufts, toward the sides on the glass are angled inward. This would be the meeting of the flow from the top and the sides meeting. It would be where those large rotating vortices begin.

Lemme gamble f on a guess for a second: you had the Sedan?
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.
