Does Crank Stroke Affect External Balance

Think of a teeter totter, put 100#s on each side equal distance from the center, and then move one out a ft. What happens? Same with crank throws.
Yes, you can use a 360 balancer, on a 408, but corrections will have to be made, but the external balance saves on the bill verses tungsten.
When you balance, you don't tell the machine the stroke, you tell it the radius of the counterweight since that is where you correct it.
