Having read as much as I can take on the complaints about meter stutter, which I also experience, I have not seen this answer.
It isn't easy because we are conditioned to be ready to click in a matter of 2-3 seconds. Nonetheless, if you see a stutter, take your hand off of the mouse. DO NOT CLICK at all. The meter will go all the way to the right and your avatar will essentially take a practice swing. It will not count as a stroke.
As I said, it's not easy to do, but when you can, it will save you from having to guess where the meter really is, and save you from an errant shot.
And for all those who think that the communication between you and the server is YOUR fault, perhaps you can explain why I have to type some characters (or space bar) multiple times (2-5) before WGT recognizes it. This is the only place on any computer that this phenomenon occurs. Count my characters here and add 30% to that number. Especially rough on a touch typer.
