You need to read what I wrote very carefully. I do NOT endorse relinearization to realign a printer with any degree of precision. In fact, I hardly use it at all in proofing. Most EFI XF users use the optimization procedure, which uses the measurement of a profiling chart (it can be a reduced one) to interpose an L*a*b* correction LUT to "tune" the final, profiled result. This is preferred because it is more precise than profiling alone, and is especially preferred when the proofer was initially set up with optimization. It can also be used to align to another printer's optimized result. (This does not always get a better match than optimizing both printers to the reference profile, however.) With L*a*b* optimization, a good output profile and print environment can be reused more or less indefinitely. When I work with a RIP that doesn't have this feature, e.g., "production" RIPs like Onyx, Wasatch, Caldera, etc., I normally make a new profile, just as you do, IF I or someone else with the time and gear to do it is available.
I see relinearization as useful in production printing environments where larger drifts are encountered and a simple procedure is needed for relatively untrained staff, especially in a remote location where direct intervention, even via Webex, is cumbersome. It has its place.

Bottom line, whether it's EFI or ColorBurst or any other RIP that relies SOLELY on a re-linearization to try and bring things up to snuff, it rarely works all that well. A re-lin is not sufficient to predict what's happening with all the overprint colors.
