Hi I'd agree with all but the "network of caps and resistors" part.
The R/C termination stuff comes from the original NIST DMTD paper. When asked about it when the presentation, the reply was: "That's what you get when you put a statistician in charge of an RF project." The R/C termination isn't a major problem, but a more conventional R/L/C termination works slightly better. That of course *assumes* that you have good coils that don't self resonate someplace in-band. It also assumes that it is an R/L/C so that you do not have any nasty peaks in the transfer function.

In the NBS design they used an effective 500 Ohms. You want to optimize for the highest amplitude. (Generally) A network of capacitor(s) and resistor(s) is usually the best way to terminate.
