Hi Tyler,

I like that discovery. It may explain differences between
drivers. If you have a densitometer (I guess the EyeOne\
could double as one) and can read some numbers 
to compare to my chart, we can get to some scientifically
valid data (!). 

As a reminder :  my numbers were the result of reading
the darkest patch anywhere along an UNlinearized BO scale.

Glad you and Ernst are testing and contesting  <G>.
