Bill,
    I dunno on the three-phase, never faced it.  My response is on the ten
individual trackers.  Have you ever seen TWO trackers that behaved
identically?  Asking for ten to do so might mean lots of tweaky service
call-backs, especially if they're installed in a nice, straight median.  If
it's a high-profit job, just be sure to C.Y.A. against precise tracker
alignment in any contract.
