This phenomena is very infrequent but has happened to me and two of my friends. Problem: The flop shot hits double the length, ie. 25 yd flop hits 50 yds, 30 yd flop hits 60 yds, 40 yds hits 80 yds. these numbers are +- 5 yds. This has happened to me 4 times in play. I also went to the driving range, hitting perfect/perfect got similar results as stated above, double the shot length. Then after a few minutes on the range it started hitting normal distance. Thinking maybe this was a glitch and was resolved, I put it aside until it did it the fourth time today during play. Also the shot was a well hit shot, not bladed; the shot made an arc in flight as it normally would.
