Yes, I fully agree that 100% is possible or near possible at least. I
didn't post it, but I did test a
small toroid (almost a corona ring = 4.25" x 16.25"). This measured a 68%
error in Ctop. So yes, I
confirmed that for myself. Also, Fr change was 20.5%. Note, the Fr change
is greater than compared to the
two larger toroids. Why = Proximity? Yes, but due to what? Induction?

Take care,
