Perhaps around 25% for a "moderate"-sized organizition, but
as low as 5% is not unreasonable for regionals and locals.
Discount spam from around the world, and I suspect the numbers
drop even more. :-)

A couple days a couple time a year of manual testing and tweaking
for "most important" prefixes usually does the trick.

Considering industry instability, one probably changes an
upstream about as often as one would tune anyway.  Considering
the difficulty one often has finding a clued rep, one probably
spends more time educating sales reps than tuning traffic. ;-)
