You need to give more information, than just pin is a few inches above left finger.
Are you right or left handed, ball name, PAP(positive axis point if known) location of CG(center of gravity) and MB (mass bias)
heres a simple general way to show this:
---P
---O-O
----------------PAP
--------CG
-----------------------XH (extra hole)
----O
--------------MB
in general the higher the pin above the fingers, the longer the ball will go down the lane before it changes direction.
