WLLH was supposed to be a simple book for relative beginners; no one disputes that. If Lee Jones had felt compelled to show all his supporting assumptions and math to justify each use of "probably", the book would run at least 5000 pages, and no beginner would read it.
I really think we're back to where
the other thread started -- the differences between Miller and Jones are differences in opinion. Opinion about a fact, sure, but a fact that cannot be independently verified.
