Lutz1873:
New player here. I am a little confused by the putting power bar sometimes it shows the green ppal and other times it doesn't. Also the green ppal sometimes appears to be wildly inaccurate? Any tips?
Actually Putter Pal just puts the lines on the bar for different percentages when you are on the green. If you have Putter Pal, they are there all the time. Shot Pal does the same for other shot types.
I believe the "green" part you are referring to is the estimator that you get when in "Practice" mode. It is only a wide range for the given distance and green speed, and does not account for elevation change. It is not much help, really.
