Yes, but in this case there is NON-repeatable error on top of theWell, since non-orthogonality is corrected by TPoint you can skip that. Likewise, repeatable errors need not be corrected mechanically since TPoint will model them out.
You are under-estimating the difficulty in correcting non-orthogonality, etc. More power to you if you enjoy doing that though.
You need to look for loose parts that are shifting, things that flop, like mirrors or lenses loose in their cells, and if portable, assure that the pier is not shifting.
