No, I will question my understanding of the RFI circuit tho. I don't
argue with results! When you read me talking about running face first
into the hard wall of reality, you can assume that I've discovered my
belief on how something works didn't match observed results. A common
place occurrence, it's quite humbling.

SPICE is a classic example of GIGO, it will present you with beautiful
looking results that are absolute garbage!

Observed results, and the school of hard arcs:)

I would.
