What a long thread...
Yup ;)
Actually this is a direct result of rounding in primitives!
The most outer point of the torus lies at x=1+1/14=1.0714285714285714285714285714286 but primitives are rounded to 4dp so you get 1.0714. Once scaled by 24.5, the error is -0.0007. So you get 26.2493 instead of 26.25. But this error is less than 1/1000 ldu, completely invisible. And even smooth shading in LDview accounts for some rounding errors between polygon vertices and condlines endpoints. That's also the reason why in Edger2 has a "precision" option to allow some discrepancy between matching coordinates. This precision defaults to 0.001, but it may be changed if necessary.
