zagraniczniak: The green itself - once you land on it - may not be sloping up at all and may even be sloping down toward the hole.
One way to figure this is to take the aimer to the edge of the green and watch the elevation change as you move it to the hole. Use that drop or rise as your elevation change but figure it starting at the edge of the green, not where you're standing.
yes. exactly. Then you have to contemplate the calculus of how the elevation of the green effects the landing angle of the ball and adjust for the roll.
If tha'ts all a bit to much to consider.. just flop the darn thing! lol. The flop is a bit overused here imo. People are just too lazy to read the green. I do often just flop it close, but more often than not I'm trying for the hole out - which usually means chipping inside of 12 feet and pitching for 12 to 25 feet for me. (if the lie allows for it)
One more tip. You will often get the elevation just in feet. This is not good if you have some number of inches up/down on the green itself - you might miss it if you just look at the footage. . In this situation you have to go by the color of the grid. I've just recently started to really consider this (as opposed to just going by memory) and it has helped me considerably.
