You have an example in numbers. Hope you are happy.

Hi Richard,

As I mentioned to Walt in similar response to my oft-asked question:
direct and to the point. I see no others yet.

I know this wasn't arrived at by direct measurement and only by
inference. As I remarked to Walt (but in the inverse), I presume
this value is that transformed through the plate tuning from the
plate's Rp? Can you provide some work-up (presumably several KOhms)
from your citation for that?
