The pitch offsets on IM3 and IM4 were necessary to align the beam to PR2 on 10/6, but not typical.
Additionally, IM3 bolts had not yet been torqued, but have been now, so it's alignment values may change by ~100's of counts.
This will be revisited with IO's next opportunity to to have the beam from the PSL.
