I realize WGT isn't Battlefield 4 or anything like that but you're still playing a game or working with an application' which is dependent on interaction between your mouse - computer.
If you want to remove a big piece of the puzzle of 'why I can't hit the ding?' Get a gaming mouse. Standard mice have garbage polling rates. Make sure it's plugged in directly to the computer, not a hub or keyboard. If you're using windows download the registry fix for raw input, not too important for this game, but still takes a layer of control out of the picture.
People don't think it makes a difference, it does. There is a big difference between a polling rate of 125 (which is around the average for consumer mice) and 1000.
Try it....
