Timing markings on balancer

[DmnStr8]

I found the markings on my balancer but have no idea on how to read them. Does it go left to right? Do they start at 0 and each mark is a 1 degree advance?

I don't know anyone that pays to much attention to all the marks on the harmonic balancer. Just mark the 0 slash with white paint and set your timing with a light that has a dial. Remember, clockwise to advance, counter clockwise to retard.

Mostly just curious and where it is now. I'm not sure if the previous owner had played with it or not.
