Some people have a tendency to play fast. The page has a few things with flash going on and this interrupts the meter. WGT needs to make the club name animation stop switching names. We know what the name of the club is. Then there's the title of the golf ball that switches back when we use the backspin feature. You also have to let the game settle-down after you use the aim-arc and/or the putting aim. This will cause meter stutter as well. If WGT would only stop the flash animation (and we know they won't) in the game client, I'd say the meter problems a lot of members experience could be reduced by 25%, if not more.
Oh yeah, don't forget about the flash banner at Oakmont in the upper right box. It continually flashes every three seconds from the Oakmont logo to the USGA logo, and this to will cause meter stutter as well.
The long of the short is, play the game slowly and let flash have a chance to settle-down after making a command, and the joy of your WGT golfing experience will be greatly increased. : )
