Digital BW, The Print

Hi Austin,

Your right about all this of course, but I dont think 
it's going to change what people mean when they use the 
term. I guess I'm used to it, in my industry there are 
several definitions of snr, all different from the 
textbook version. Most of the time when someone uses 
that term with me it's to tell me that something is good 
or bad, and I dont need to know more than that. When the 
situation warrants it I'll ask very specific questions 
to be sure I'm getting the right info. And, yes, over 
the years I've been burned a few times because of the 
ambiguity when I wasnt careful enough. Same thing 
applies here, except for right now, because you've 
diligently put out all this info and explanation, but in 
a week or so all that will be forgotten. Just my 2 cents.
