I asked this last week. It only seems to happen to me on iron shots or maybe those are the ones that you notice more. My example was on #14 at Kiawah where I hit a perfect shot dead center and it misses the green right. They called this the Beast, it reminds me of the movie Broken Arrow, where they lost 2 nuclear weapons. They called in a code Broken Arrow, which is code for lost nuclear weapons, the guy said he didn't know which was worse, losing the weapons or knowing we had a code for this happening.
I think we should rename the BEAST to an appropriate 4 letter word.
