andyson:Wouldn't stopping the timer provide an opportunity to buy more time during a shot?
Thank you andy, this is a very good question, and I admit, one I hadn't thought of. I'm assuming you're referring to the possibility that if the timer stops when one starts the swing, they may whiff it thus extending the timer? I personally have never tried this and don't know if it would work or not. I'm not in the habit of looking for the "advantage" to any suggestion(s) I've made, only to the fairness to all, side of things.
If it is possible to whiff a shot and extend the timer, I clearly see the reason for WGT making the contact with the ball the stop timer point. With this in mind, I drop my suggestion for consideration.
