Tim: I'm quite aware of color science. I teach color courses around the world, take color courses, and attend professional society symposia on color where I talk with top experts in the world. I'm one of the top color scientists in one of the largest corporations in the world. I develop calibrated color imaging systems full time, all the time. I think you misunderstood the intent of this submission, which was to simply create an image using the X-rite supplied values of their Color Checker chart. Nothing more. No one who images a real chart should expect to get the sRGB values. No one would be able to use this image for any calibration or anything at all other than creating a synthetic image, which is all it's meant for. I'm sorry you expected more, despite my disclaimer in the second paragraph of the description, and gave it the lowest possible rating.
