Chart for various stock advance curves

Here's a governor slot length to degree chart. Includes both crank and distributor (cam) degrees. I needed 10 degrees, so I had to kinda shoot from the hip. I used a protractor and measured 5 degrees at the distributor and welded and filed the slots accordingly.
