Yeah, I think you're all right.

It didn't occur to me until I started thinking about wind specifically, but I didn't really see the hood flutter on the way back. Maybe a tiny bit here or there, but nothing that stood out.

On the way down there was definitely a fair amount of dancing going on from time to time - likely when the gusts picked up.

Wind speeds were around 10-15mph following on the return trip, out of the south or southwest depending on where along the map I looked, and the drive was pretty much straight north so there really wasn't anywhere I wasn't getting a boost. The road snakes around but not enough to be really fun, and not enough to really have any stretch of time where you're broadside to the wind.

If I'd thought about it hard enough I could've answered my own question: the reason you do speed records with two runs - one in each direction - is exactly for this reason. Otherwise it would rely too much on who picked the right track on the right day with the biggest tail wind.
