This was discussed ad nauseum, about a year ago, on the 
Epson list.  I suggest you check the archives of that list.

To ask "what percentage of the world deals with excessive 
ozone levels" is a bit like asking, "what percentage of processed 
film has excessive curvature"  -- if you catch my drift.

For Epson engineers (or Henry Wilhelm) to have ignored 
a common atmospheric oxidant is an error of omission of 
no less magnitude than Nikon engineers ignoring the fact 
that processed film often has a third dimension.
