Wouldn't leaving the middle two open provide more of a cooling benefit? Or is the point to leave those covered?

I don't know, the only discussion I've found about what openings to leave open is for an XJ which has the viscous fan and the owner openings in front of the viscous fan open for correct viscous fan operation.
My Jeep has a hydraulically operated fan, so no need for that.

Trip done, now for some numbers:
First tank, over 393 miles of highway (reference section) - 31.65 calculated MPG, 35.1 indicated MPG
Second tank, over 425 miles of highway and 120 miles of mountain roads (commute to the ski slope) - 28.2 calculated MPG
Third tank, over 457 miles of highway - 29.66 calculated MPG - strong side winds

Average MPG over 1396 miles - 29.586, indicated MPG: 33.128.

In L/100km, the difference between indicated to calculated consumption was 0.7L/100km for the first tank and 0.8L/100km for the trip total.

The trip from 2016 had an average MPG of 29.549. For that trip I had a stronger chin spoiler and the lower grille block.


You can see here that the chin spoiler bent back. I will modify the mounts to make it stronger and easier to install/uninstall:


Here it's obvious that there is a lot of road spray on the chin spoiler and almost nothing on the tire deflector past the bend. Should there be spray there to show attached air flow? Corner wear from tire contact is also visible:


This is how far back the deflector is pushed when going up to 85 mph, the highway was very busy and sometimes passing trucks required going that fast.


Back to the drawing board for the deflectors. I'm open to suggestions

Also, I'm an idiot with the grille block, I should've read this first:

It's easier when you start with a Beetle.

It's not streetable, in fact they had to remove the splitter to get it on and off their trailer.

I remember reading the topic with that.

Honestly, I don't know if the car felt more stable at highway speeds because of the deflectors or because I replaced some worn control arm bushings
