A couple of times this year a team member has asked me the distance to the pin and I gave it to them. Both times they hit the ball over the green and in trouble. One in the water and one in the woods.
Both times after they hit the shot they said "There is no way that distance is right."
Since I use a GPS I couldn't be completely sure so I borrowed a friend's range finder later and went back to those spots. According to the range finder I was 1 yard off on one and right on the number on the other. If my GPS had been off enough to cause those shots I would have pitched it in the lake.
Both of these guys are very good players (much better than I am).
In my own game I have an idea what my distances are, and use that information to pick a club, but the distance I hit any particular club can vary by quite a bit depending on what I am seeing and feeling. I'm basically picking a club and swinging as fast as I feel I need to swing it to reach the target.
I decided to make this thread after reading in another forum where somebody lost 5 yards using a certain ball.
I would have to hit many, many balls and probably have to hit different balls alternately to even come close to knowing that for sure. Even on what feel like equally well hit balls my driver distances can and do commonly vary by 15 yards or more even with the same golf ball.
