Yeah I confirmed that my balancer is indexed correctly to my pointer (mine is driver's side)

This is great info... thanks!
I also saw 20 degrees added by the vacuum cannister, so good to know that my dist. is acting the same as others of the same model.
I am leaning toward the same conclusion as you about the vaccum advance on mine being "impeded" before saturday night, and suddenly having something work loose which allowed it to go full vaccum. I didn't see anything loose floating around inside the dist. housing when I had the cap and rotor off it, but I'm going to take a second look at that, because I think you are onto something....
