Gates claims their GT2 belt has zero stretch, you "deduced" that the stretch is 1.85 mm.Quote

I interpreted it one way and deduced elongation of about 1.85 mm
That's a lot of stretch for a 6.423 pound-force.
To put this in perspective, you could easily test your deduction simply by tensioning the belt with your hands.
Place two marks on the belt 1 meter apart, and measure how much they separate.

0.2 N/m / .007 m = 28.57 N
28.57 newton = 6.423 pound-force

A2, I needed a break from this discussion. But I'll give you one more chance. Maybe you made only a mistake (maybe you are not trolling me).
Why should I use a script which is different from mine and from the one specified in the Note 7 of the Gates document. In your script, the definition of B should have been: 124105648 * Newton / meter²; (Because the unit for their "modulus" was lb/in². Because you changed the problem without any explanation why you are doing so, it looks like you are trying to pull out a Straw Man.
I show the math of the Gates formula, and I provided you a link to help you with the modulus conversion.
You can check your hand calculated modulus value against the on-line calculator.

Even If I would try to use your script (exactly as you have written it), notice that you got the final unit of elongation (meter) in the position of a denominator. That means that you are actually proposing to measure distances in units of 1/meter. Does it not sound bad to you? Distances are typically measured in units of meter, not 1/meter.
You don't divide your answer by the distance.
The output is the length that the belt will stretch per 1 meter.
That's why the wxMaxima software shows you the result over the span of interest.
