But this one has another line contributing to total boom movement...the black line on the extreme left. So won't is be 8:1 + 1:1 = 9:1?

So just for practice, this one is 2 x 4 = 8, correct?

It looks like the black is a cascade doubler and the red on the left is 4:1.
The red-right is ineffective, turning only. [Linked Image]
