I think these errors are too high. Average should not be higher than 2 with a max of 6, if I remember correctly, depending what media you use. Some of the patches of the CC24 are out of gamut of a proofing space like SWOP_C3 but not by 11!

Is it possible this is related to the age of the target, and if so, how long should one be kept before replacing?
