If the deformation of your ShapeArray (SAA) is quite significant and appears to originate and grow from a point near the bottom of the ShapeArray (see for example Figure below) then most likely the ShapeArray has undergone some significant rotation over much of its length. For a detailed discussion of the effects of rotation and how to correct for it, please see: 'Effects of Rotation of a Non-Horizontal ShapeArray within its Conduit'.
