There is video of the James Taylor tuning method on YouTube, by James Taylor himself. His way depends on using precise digital tuners for repeatability. I came to similar conclusions years ago, by ear, before discovering his video, and I still do it by ear, because every guitar is a little different. Modern Peterson strobe tuners and some others have "sweetening" modes that produce a similar outcome.

The end result is that the strings get increasingly flat as you go down, with the low E quite flat (like 18 cents or something). I like doing this by ear, because it varies by guitar, and also by tuning - I often use non-standard tunings, and modal tunings want a different sort of sweetening due to the octave and fifth relationships.
