For those of you who don't know it, you do NOT have to click the mouse just because you started a swing.
If I see the slightest glitch or hesitation, I lift my hand completely off the mouse and let the bar continue to the end so I can start over.
I have found my natural instinct is to try and catch up with the errant meter, almost guaranteeing a bad swing, that's why I lift my hand completely off the mouse.
The animation will take a practice swing, but it doesn't count as a stroke.
I once had to wait through 3 swings before I clicked on the 4th. After the second, a message pops up with an arrow showing you where you should click.
To minimize meter issues, I have installed Chrome just to play this game on (after reading numerous forum posts extolling its virtues).
I can report having fewer issues with the meter since installing it. Still use Firefox for everything else, but on WGT it's Chrome for me.
