511 Steering Geometry

That image you originally posted explaining "ackerman measurement" is probably some standard used by the automotive industry. It's not truly representative of what is actually happening dynamically. The same can be said for roll-center as well. Static measurements and their definitions do little to explain suspension dynamics (as you're finding out).

Now what you found could be usefull is you were to go high-speed racing. The reduction of dynamic ackerman could be used to your advantage. Perhaps in extremely high-speed turns where you're not looking for a bunch of toe-out in a turn. Of course only back-to-back track testing would tell for sure.
