MP Dizzy?

Does it have anything to do with the fact that the distributor rotates half as quickly as the crank? Crank degrees are different that distributor degrees.
I believe so, part of what I'm trying to confirm. That's also why I said 25 degrees into distributor when there's 50 total at the crank. I'm still trying to learn so, so I could be way off on a lot of things regarding this stuff.
