It gives a quantitative measure that enables you to compare how 
consistently a monochrome image is being scanned.  Since it's against a 
standard material, Wratten 96, anyone can do it and it gives a method to 
compare machines.  I want to contribute a few numbers to the hot air.

I've updated the page.  SF makes no difference.  I added multi-sampling to 
show what a difference that makes.

The LS-8000 is a 14-bit scanner.  I originally ran the test to get an idea 
on how accurate the bits were.  It seems to me that it's at the 2^0 
bit.  As for the 6 bits below it, I assume they're for show.  So much for 
the merits of 8+bit scanning.
