Saratogan:
is it just me or are most putts downhill? I have a downhill putt that I putt past the hole and my putt back is also downhill. Is this even possible? I have been keeping a mental tab and I think that 60-70% of putts I am presented with are downhill.
On average, 50% of putts are downhill. Guess what the other ones are?
Anyway, don't just rely on the aimer elevation. The elevation changes direction on many, especially longer, putts. It may go up and down before it gets to the aimer. Thus, your first putt may have been downhill until the last part, when it went up some. So, when you go back the other way, the aimer may be sitting lower than your location.
The putting grid colors also show relative elevations - darker bues higher than lighter and both higher than oranges and reds.
