VPI Classic Azimuth Seems to Change -- Normal??

I own the VPI Classic with a Classic 3 wand upgrade. The Classic 3 wand is stainless steel and incorporates Valhalla silver wiring. My carty is the VPI Zephyr. My set-up is pretty straightforward.

Here's what I noticed. I was checking aziumth and some other settings. I'm pretty sure that the azimuth changed when I moved the arm to the inner tracks. It was pretty stable in the middle and outer tracks. It seems that the Valhalla wire in some way is twisting the arm causing the change. To try and minimize the effect, I tried not to twist the wire, but to little effect.

Any thoughts, comments or suggestions?
