Hi Jeff,

I believe that in theory the divot should have a base straight line because the hosel of the clubface travels down and out the inclined plane.
This is due to tracing: You can picture this by moving your clubshaft along a bench: The clubhead will travel down-out-forward, go to low point, then up-in-foward while tracing the line.

So, the base of the divot (near the hosel of the clubface) will be a straigh line and the divot deeper at low point.

However, for the toe of the club it's a different story because it is constantly closing. So the upper part of the divot could probably be a curve.

Now, if you destroy the ground as I do, it ends up as tough to read divots as to read into chiken entrails! (Bucket's entrails?)
