Then you guys need to get with Gibson and tell them to quit giving false information. Because it's clearly stated on their website and I just did a simple copy and paste.
http://www2.gibson.com/Products/Electric-Guitars/Les-Paul/Gibson-USA/Les-Paul-Studio-Mahogany.aspx
Just scroll down to where it says "Headstock Angle".
There is a ton of mis information out there. Sadly a LOT of it is promoted and propagated by major brands in an attempt to sell their products. This wouldn't be the first or last example of the industry making false claims and issuing over promises.
The relevant bit of physics you need to disprove it is below. I have cut and pasted an image of the expression of the way in which a vibrating string behaves. It is taken from research done by two highly eminent and regarded research physicists named V.E.Howle and Lloyd.N.Trefethen and is lifted directly from their paper entitled "Eigenvalues and musical instruments"
As you can see the expression makes no mention of variables for tension or break angle at the fixed points mostly because they do not come into play. It does very nicely and compactly describe how a vibrating string behaves both theoretically and in practice. I'm sure you'll agree this is a very nicely described model..
I'm also sure both you with your in depth read of the Gibsons advertising blurb and ReInventor with the wealth of research background and qualifications in musical acoustics and MT that he has will either be familiar with the paper or will find it easily accessible. I can provide a key to the terms employed but it shouldn't be needed as they are all commonly used in the world of mathematics and physics.
In the unlikely event that either of you find the expression a little hard to grasp I can talk you through it starting with the principles of mass and inertia and finishing with the impedance (Q) factor in relation to Youngs modulus in solid crystalline materials. Should take around 7 -10 years depending on your start point and aptitude for the subject.
Here you go....
