From what I understand, Flash Player and it's layers imposes a plethora of restrictions.
Add in the complications associated with multi-player games.
As mentioned many of us note the lie, distance, and wind at the end of our shots.
While another player is up, I then check/review my mental or written notes for that hole. I decide:
• What club I'm going to use for my next shot.
• How hard I'm going to hit the shot.
• Where I want my ball to land in the fairway or on the green.
• If the shot allows, how much (if any) I want the ball to roil or back up after it lands.
When it is again my turn I will have already made all the major decisions for the shot so all that is left to do is - set my aim point, set the ball spin (if applicable), choose my shot type and club, and then hit the ball.
