This bit from the ELOG entry: "Adjusted the stepper motor until the encoder value read 118407 when the spool weldment was compressed to 107.4mm." suggests that they deliberately rematched the drive-table location to the correct (old) encoder value, preserving the old calibration.
The encoder(118407) = 107.4mm correlation can probably be checked against
the previous calibration(?)
