MrFunnyWobbl: Yes meter has it's good and bad days. We all deal with it. Such is life.
Many WGT players have a smooth meter pretty much every time they play WGT.
A smooth meter is about the maintenance and set up of your computer.
The bottom line is the meter plays on your computer. Consequently, if the meter doesn't consistently play smoothly on your computer the first thing to suspect is that your computer is doing something, or some combination of things, in the background that is keeping your computer's CPU busy. Your CPU is dividing it's time between those other things and playing the meter on your display.
You want to start the downswing when your CPU is almost quiescent. That's why many players monitor the performance of their computer CPU using Task Manager as they wait at the top of their back swing.
