Rotor/Reluctor Phasing Question

Nice article with the exception of a post by Chryco Psycho, he deviates from the laws of Physics in this world. Ported vacuum at WOT greater than manifold vacuum, no way!

At best, tuning a mechanical advance distributor is a compromise. The RPM and vacuum curves are independent and do not include temperature, and smart interrelated compensations. Modern OEM ignitions (post 1996) are much improved with improved sensing means, 3D tables, and knock feedback.
