Experiment with the drift fitting algorithm, don't just accept the default. You may find a better (read tighter) fit with a different algorithm.

This is why, as part of understanding the characteristics of the mount, i also like to compare long datasets from different runs from different true sky positions. The "drift" fitting is not only dealing with drift, it also deals with tooth spacing errors etc on the final wormwheel.
Running the PEMPro display in "non overlapped" mode really highlights this well, and displays why PE aint always PE.
ie the PE model will work well in some places but not so well in others.
