Where to look next to the explanation is great. Treat it as most don't have the book, but those that do will have the number next to it to look up. I do occasionally, but it's easier to understand straight from the horses mouth then trying to diasect the bible of golf.
I just remember posts that looked like a foreign language to me.
One reference leads to another,
that leads to another,
that leads you to yet another
and so on and so forth and
next thing you know
you are fluent in Kelley.
And that goes straight to the hands.
The references are handy as a footnote tool, so to speak. I will reiterate the above that a response of a reference only is annoying, and more of an ego thing. Drives me nuts when someone makes a post consisting of nothing more than, "6-E-2."
Mr. Kelley put reference in the book for a reason. It is up to the individual whether or not they decide to use them. Having references will keep everyone happy(3-A) .
