Thanks. That's what I was anticipating as well. I'd think wheel isolation for the 3rd wheel would yield results.
The thing is, I'm not finding contact points at all unless I rapidly spin the dial, and that causes me to overshoot them and not be able to quantify them.
I see an autodialer in my future.
I know some people have used audio tools for the forest bit. Once you find a number the cl’s should get stronger.
Sometimes putting pressure on the handle can help give more reliable contact points is my understanding.
Before autodialler it might help to see if a quick run of AWL or AWR reveals a position where contact points show up clearly, not necessarily looking for reading improvements other than strength of the contact points.
