Honestly the thing makes my head hurt figuring it out.
But here it is.
At least for mine.
I have the charts but I wanted to "back" figure it to see if I could come up with the numbers by using math.
Have no idea if it is the right way but it works for me.

My rotary table has a 90:1 ratio it takes 90 rotations of the handle to make it go one revolution.

I want 100 divisions with this thing so what to do.
100 divided by 5 = 20.
I have a dividing plate that has 20 holes in it.
But I have a 90:1 ratio.
What goes into 90 5 times, 90 divided by 18 = 5.

So I get the 20 hole dividing plate and use it to move 18 holes at a time.
This will give me 100 of anything evenly spaced in a circle.
