Color Fidelity (Score -1, Redundant)

The problem with this approach is that it only works if you have already calibrated the color for your inkjet printer and the specific paper you print the target on. Even on the same printer with the same ink cartridges, the color will shift around a little bit for each paper you use. If you then use the "shifted" target to do further calibrations, you're calibrating to the wrong profile.
