Thanks Roger and David,
Yes, I know that more doesn't necessarily mean better. I have a client who
is insisting that he 3needs2 4000 patches because he feels it's given him
better results than the standard Macbeth 918. We didn9t generate that
profile, so I have no idea if he has a case. I may try to convince him to
let us try quality not quantity first!
Thanks!
James
