There are some interesting pages about scopes on the Olivon website. At:
http://www.olivonoptics.com/index.asp?PageAction=Custom&ID=12
they say:
"From $200 to $2000, each time you double the retail price of a spotting
scope you can expect about a 10-15% improvement in optical performance."

That would be US dollars, I guess. Applying that formula, a $400 scope
would be 15% better than a $200 scope, $800 would be 32% better, and
$1600 would be 52% better.

A lot of money for only a 52% improvement.  Any comments?

No, they don't define "optical performance".
