Does any one use a grip where your thumb is say 3/4 of an inch to the left of your center line

what does this do? Why would one use it.

Depends on the bowler. 3/4" is pretty extreme. My thumb is 3/16" left of my center line and it's for comfort. I just feel twisted otherwise. Thumb flexibility has a lot to do with it. Different amounts of flexibility call for different amounts of pitch/offset in the thumb. Jeff Carter uses an offset thumb with obviously a good amount of success.

I went to a clinic in Vegas last year and they were promoting a grip like this- I cannot remember the term for it. The reasoning is that it is the natural postion for the thumb and alows a much cleaner release and you are able to set the ball more on your hand. However have not tryed it. It did seem reasonable. The clinic was a BTM super school.

If you are lining up your center line based off of the fingers, than you are over analyzing your grip. Your ring finger will generally be longer than your middle finger giving the perception that the thumb is offset to the left.

The "offset" thumb was first used by Bob Strickland as far as I know. He has a drilling that is supposed to line up the center of the ball with the center of your hand. His therory is that if you partially close your hand similating the grip of your ball, you will notice that the thumb is "offset to the side of your middle finger, thus the centerline of your ball lay-out should be through the center of your palm, not the center of your thumb. He also used 3 different center lines to drill a ball. One for the middle finger, which was conventional, One for the the thumb, which was through the centerline of the middle finger, and one for the ring finger which was though the center line of the thumb.

So how does another shop duplicate the grip, not knowing that there were multiple reference centerlines

They will draw it up and measure it out like any other ball.

Line through the center of the thumb and between the fingers for the center line. and then the midline at the center of the span.

They will then measure from the thumb to each finger for span length.... and then measure the pitches with the center line and midline being the reference points.

That is why you can call it whatever type "thumb" you want but there is no such thing as an offset thumb by the definition of how you draw up a ball to measure it and duplicate it.

If you take into account the CLT angle when fitting a ball it will take care of the "offset" thumb issue.
