The pin buffer is a measurement that affects the pin height and the mb by moving it closer or farther away from your vertical axis line.
Say you drill a 4x4 pin, mb, to pap. You could choose a 1 1/2" pin buffer giving you a longer and stronger backend by having a higher pin and the mb in the strong position. If you went with a 3 1/2" pin buffer it would lower the pin height and place the mb close to your vertical axis line giving you an earlier roll but continuous controled movement.
The trick layouts that ebonite has been showing are similar to using a pin buffer that is very close to your vertical axis line. They just measure out the ball with degrees and then find the pap that way then they use the same technique of drawing an arc around the pin then creating a tangent to find your VAL.
Basically you choose your pin placement to find how much flare (in this case 4" for strong track flare) and your MB Placement (4" stacked for a strong midlane and backend) then you can fine tune it with this measurement.
Hope that helps.
