Agree. However, misfires and irregularities in the gap makes 
themselves known to the shocked. The output of an ignition coil rings.
You know what that feels like. It is hard to generalize for a TC. 
Sometimes you feel nothing, other times.....  I can say from 
experience that a coil run with a high primary energy content is 
certain to give a few belts whether run repetitively or not. One 
cannot explain those observations by considering Fr in isolation.
