Tempo of the round is critical to my performance. When I play in single player I am a very fast player. I need to maintain the rhythm, when I start to get meter issues and have to take 'practice swings' it actually throws my timing off for a little while. On a good round I can usually ding well over 50% and the others are 1 pixel misses with the odd 2 pixel miss thrown in there. As for the method, I'm kind of a hybrid of A and B, I'll focus (although not intently) on a point a bit before the ding and when I catch the meter in my peripheral I will follow it to the ding, aborting on any abnormal speed. Of course it takes practice to master it (forgive the pun).
And another tip that relates to your pace of play, and for those that have more playing experience than the average WGTer.... Trust your first instinct!! This is crucial! Unless you miss a glaring variable... your first instinct will usually be correct 90% or more of the time. Second guessing hurts you in 2 ways, it casts doubt on your shot reducing confidence, and it destroys the rhythm of the round.
