Thank Tom Knoll�he built the feature! The white-balancing is done in step 3, on the second-to-lightest gray patch�it's in the tutorial. It's a sufficiently detailed and lengthy procedure that I can easily forgive you for missing it! I've found that with a great deal of work I can make all the gray patches match the target values except for the white one, which is always a bit darker. Having now done this about two hundred times, I've come to the conclusion that as long as the gray patches are neutral and within about 5-7 levels of the target value, that's good enough.
