First off, what's a 'precessional alignment'? That the procedure the guy at the end of the street is advertising for only $29.99 (pickups and SUV's slightly higher)?

Let's define our terminology. By definition, precession means something moving. If it's going to align with anything, that alignment only lasts for a split instant, then the whatever has moved on. The phrase is a bit oxymoronic to me.
