Sounds plausible, and the MathSoft estimated ratio is more like 30 (but
then their user base will have a more hierarchical support structure).
As I don't know who here is signed up to R-help (but I do for S-news)
I am guessing a bit, but I'd say we had a 20:1 ratio (at uses R for several
hours per year) in my dept for each R and S.
