Man I wish I had to patience to do that, Tiffer. There's too much stuff jammed into the mind cache! LOL
I'm noticing something fairly consistent with aiming the longer putts but it's still in the infancy stage as far as empirical goes. On longer putts where you have a good look at a lot of dots there are usually 3 or 4 dots that roll in a fairly straight line together, much like a pencil would on an incline. There may be several places where you see this and if you can imagine them as a straight line, look to where they first appear out of the green-where they first start rolling. Aim parallel to this imaginary line. You will be surprised at how close the roll is if your speed is right.
