Didn't they do the same piece a year or two ago?
I doubt many people don't dodge/burn at least a little. So the point that you can just dial in a grade and be done with it sort of flys out the window. The other issue is for some of us it's a more visual method. One thing I gain from spilt filtering is seeing . I can't jump to the conclusion a print needs a certain grade with the same ease. Not to mention for me it's quick and relatively painless.
