Would it not be truer to say that the good ones tend to have a 
closest to that slope?

I have been following the arguments closely. I perfectly understand
the point Peter is making but have doubts that it is a valid one. I
haven't reached a conclusion and await further enlightenment, perhaps
from a professor of applied statistics, i.e. in my ignorance I make an
appeal to authority. It is curious how in such intense discussions
phrases such as "closed mind" crop up. I think an open mind is good,
but try to take care that mine is not so open that my brains drop out.

Ouch! Do the end points lie on the horizon?
