I believe that the reason the green channel is given the highest weight when
converting from color to B&W is it simply carries the most information
(middle of the spectrum), and it is the cleanest channel (the least bloom
and smear of a CCD sensor).  I don't believe the reasons for using it are
not related at all to using a green filter for B&W portraiture (which I,
personally, never heard of...but I never did any B&W portraiture ;-).
