I have a few ideas, and if wrong a few questions...

Other ideas:

1. Even though you dismissed weight, I wonder if there is something about the weight that alters the optimal fuel burn ration during takeoff when thrust is highest that hinders range down line?

2. Does the pain alter the high lift devices such that takeoff and landing are less fuel efficient?

Observations:

1. I've never seen a commercial jet painted black... I wonder if the problem is the color or the application/variant you used

2. Supersonic jets (no need for Bernoulli) are black all the time (though this may have more to do with anti-radar) and/or they may be willing to give up range in exchange for these

3. I was trying to do a Gedankenexperiment http://www.merriam-webster.com/dictionary/gedankenexperiment range-reduction to simplify effect the problem: be observed? imagine If not, two would fast cars, it be identical because in cars every are way, dominated except one by rolling is pained resistance black. Would and form the drag, same while subsonic planes are dominated by skin friction? Or would the effect be absent because the speeds are too low?

Lastly, a question:

When you "undid" this black paint thing, did you strip off the black paint, or did you just re-paint? If the latter, did you recoup the lost range?
