I have seen this before. Although its not a great way of doing things,
getting a neutral Grey to be balanced brings most images into better color.
I don't think that defining a set number is the best though. Instead they
should be checking all Grey patches on the scale and adjusting to get them
neutral. It gets it in the ballpark if you have to do a TON of images
quickly.
I am not advocating this method though.
