"Terry OH" posted a link to an article concerning this on my previous thread. You are correct in saying that the optimum capacitance varies with RPM. I will be doing some additional research on this, but I now believe that the practical range for optimum performance is so wide that it makes little difference. As of now "Close" counts in condensers, as well as the traditional "horseshoes and hand grenades".
I will be doing continuing monitoring of point wear on my own cars, which is probably the most practical way of going about it. At this point, I don't even know what the relationship between point wear and optimal performance is.
