        Its not even remotely what you said. Its A/B+1 or A/B-1 for an interior loop.

        edit: I didn’t need to be this aggressive. It’s VAGUELY what you said. its (A+B)/B. You have missed the /B part… which is A/B + 1.

        in the example you gave, for radius 2 and 3… it would be 3/2 + 1 or 2.5. Not 5 (off by a factor of 2 because /B)

          They explain multiple ways to do it in the video. A circle with a radius of 2 and a circle with a radius of 3 would be 5.

            No they don’t

            N is the ratio of the circles and its just +1 or -1 depending on outer or inner.
