I would hope not. Most distributers come from the factory with a curve that starts around 1200 rpm's or so.
Check the mechanical advance on ANY distributor OEM, MSD, etc. You will find that there is some looseness or "Slop" in the springs and their attaching points on the flyweights that will allow movement (remove the cap and rotate the rotor)that translates into approx 4-6 degrees of initial advance when the distributor first begins to spin. Then the inital resistance force of the advance springs marks the begining of the upward slope of the timing curve. In the case of MSD's the diameter of the chosen bushing (coded with various colors) limits the overall travel of the flyweights and reluctor (trigger wheel) to "Advance the timing".
