Good work, Steve, but I'd love to see this data plotted as curves with 
log R vs log f.

Your discussion of the importance of R is also veyr good, I think you 
ought to reference my prior publication about this, which I first did in 
2005 as part of an AES paper, repeated in a long app note for audio 
guys.  Both are on my website. As you can see from any of my work, I try 
to credit others for their contributions.
