Hi Leroy - I didn't work out your calculations, but comparing the result after
adding:

torus {3, 0.005 texture {pigment {White} finish {diffuse 1}} translate y}

Shows it to have a bit of a VISIO "squircle" thing going on.

Adding #declare CL = CL*0.985;

Makes it noticeably more circular.


If you want to tweak it:
