vacuum advance ?

i ordered a new one for it. i was just wondering if the amount of adv. throw was due to the dwell that was necessary for point vs. elec.. the reluctor / magnet setup must make it different due to sensitivity of magnetic field or something. l'm gonna do some more research to maybe find out and i'll post something on my findings.like i say, i was just wondering. i like to try to find answers to these little questions. they make me feel a little more knowledgeable. and it may help someone else along the way. thanks dave i appreciate the help. postcar.
