I have noticed that sometimes the elevation at the ball location on the green is not zero. When not zero, it is usually -1.
As I understand it, all elevations shown should be relative to the ball location (anywhere on the course, actually), so how could this be?
More importantly, should we ignore that or just use relative numbers in this case?
For example, if I have a putt that shows a drop of 6 inches (-6 at hole), but the elevation at the ball is shown as down 1 (-1), would you assume a drop of 6 inches or 5 inches?
I use the relative distance (-5 inches in the example), but don't have enough experience to know if this always is better. Anyone have any input?
I suppose I should get on the putting green and see if I can duplicate this and test it.
Enquiring minds want to know!
