Drawing the letter 'H'

[JohnSmalls]

Guys, I saw an article in the past few weeks about on course stat tracking.  I think it was from a long-time caddie.  He said he draws an 'H' on an empty page in a greensbook, and uses that to track his pro's driving and approach accuracy through the round.  I thought I saved the article but I cannot find it anywhere.  Do any of you have any clue what I am talking about?  Is there any chance you can lead me back to that article?
