slimjym: Even then, I'm not sure I'm using it correctly. Can anyone direct me to instructions for correct usage?
Like Z pointed out, you only see that in practice mode. As far as how to use it, there are no real directions other than aim, take your swing and watch the putt. Being a preview, you can then move the aimer wherever you want and then take your real swing.
It's a good way to figure out how the speed of the dots and the actual green speed affect the putting arc as well as dialing in your putter for distance. Hit the mulligan option to try again.
You can set up a practice round on any course and you'll get the PP option, it doesn't have to come from the OBJECTIVES box. The key is practice mode.
