Lgraef,
During the time that I lived with the Ruby/Graham combo, I experienced two periods of mistracking with the Ruby both of which were eliminated. The first was caused by too much damping fluid in the well. Once I got the damping tuned (less than the recommended amount), that took care of things for quite a while.
The second occurrence happened when dust had built up on the cantilever unknown to me. I clean the stylus regularly but never looked at the cantilever. It wasn't until I was switching cartridges and had the wand off the arm that I noticed the build up. I cleaned the cantilever before proceeding with the switch and that took care of the mistracking I was experiencing.
