Anyone who enjoyed the ring discussion might also enjoy analyzing this
"interesting twist" :

BTW, that's a link to US Patent #3267406.

I don't know about everyone else but I have been enjoying this
discussion tremendously, even if it is a little like debating the number
of angels on the head of a pin.

On the practical side I have to wonder the merit of such an idea. Living
in the real world, I think it highly improvable to make a perfect ring.
The lack of homogeneity in laminate, the dispersion effects of the PCB
material alone, are going to increase jitter. I will not file this one
away in my bag of tricks.
