An ineresting point, But (there's always a "but") the distributor spends very little time in a "static" position. It's always influenced by either the vacuum retard or advance unit on the distributor (early cars with one fitting only have vacuum retard) or the mechanical advance. With static phasing, how can you compensate for those variables? What difference does it make where the marks are on the cap contact? I've never seen this "problem" before.
I'm trying, but I just don't get it. Though I understand that the existence of "IT" is not JUST to be gotten by me. What was the problem you were fixing?
