Claire, I am afraid that you won't be able to make those who know about the Miller Method share their knowledge, because they have taken a silence oath when they were initiated in the Miller Methodist Circle (MMC), an underground organisation of those using the Miller Method.
The MMC members will never admit that they are part of the cult, and I think those two guys, Dave and Donald that made fun of your question are part of it. They just try to ridiculise the thread in order to shift our attention and let us think that the whole matter is unimportant.
What we should take under serious account is the possibility that the MMC might make a move in the future in order to overthrow the present leading regime in colour printing and establish their Method (the Miller Method) as the new age colour printing standard.
So, be aware...
