Hi Josh - that's kind of what I'm getting at. If it is flexure in the optical train, the guide chip should be guiding it out. If the guide graphs are that good, then the guide chip isn't seeing the same movement as the imaging chip.
Only external-to-camera things I can think of are vibrations at a frequency higher than the guider will register, but they are unlikely to induce a linear error. Have you tried turning off the cooling fans?
Anyway - good luck!
