Also, the vast majority of the wear is directly across from the cam gear. Cam is not bent, nor is the wear on the dizzy gear uneven, as stated earlier. I check and straighten, if needed, every cam I install in an engine. You'd be surprised at how many cams are bent to a certain degree right out of the box. Most are .002"-.005" bent, but I have seen as bad as .025", which was unstraightenable, and sent back to manufacturer. I bet most builders never check a cam for straightness, and just assume it is straight. We check, straighten if needed, and polish every cam we use, whether we bought it or the customer did. Not very often are they perfectly straight.
