A couple of things have become clearer since I wrote the tutorial.

1.) In theory, you should be able to perform the calibration using any of the four supported working spaces in ACR. In practice, the results are a great deal more predictable when you do the calibration using ProPhoto RGB. It doesn't mean that you're locked into ProPhoto RGB for other uses, it's just a lot easier to do the calibration that way. (Possibly because ACR uses a linear-gamma space with ProPhoto RGB primaries for a lot of its processing.)

2.) The optimal order for making the adjustments in the Calibrate tab seems to be

Shadow Tint
Green Sat
Green Hue
Blue Sat
Blue Hue
Red Sat
Red Hue

Thanks for the kind words!
