Patrick Wallace has said a recalibration after is totally unnecessary.

Sorry dude, not from my observations. Your synch stays where the original synch was, I start from there and build a new one after I finish the alignments. Else, you'll notice that while your pointing is repeatable, it will be offset by the last adjustment you did after you conduct a home/switch off the mount. I spent a lot of time trying to isolate this issue, deployed various time solutions as I initially thought it was time source based. I could be wrong, but thats my process and it works, I don't end up with a silly offset. I've seen it on both the PME and PMX, MKS4000 and MKS5000.

edit:
Just to re-iterate, once i've done a few runs and perform my last polar alignment adjustment using the wizard, I blow it all away, do a new synch, then build my actual model.
