Gentleman could it be you guys are talking different cf's? Homers vs Newtons or whoever? Check the glossary. I don't believe they are one and the same.

My book is in a container somewhere on the Atlantic Ocean at the moment so I am unable to check it. But I did check this thoroughly earlier. HK's definition is golf specific. There's nothing wrong with it, Newtonian wise. Not in the book as far as I can see, but this is one of the areas where TGM doesn't spell it out, where there's room for interpretation, and where some of the interpretations being used have flaws.

I can say more about this later, if I'm not stigmatized as believing I think I'm smarter than Homer. Right now I have a golf match to catch.
