It's really quite simple.
1) Set a delay of 2 to 3 seconds between guide exposures. No need to chase gear errors because there aren't any.
2) use whatever exposure time you want to get a good signal/noise ratio (usually from 1 to 5 seconds)
3) use Guiding assistant to gauge the seeing and set your MinMove to what is recommended.
4) depending on seeing, the aggressiveness can be set between 50% to 90%.
Be sure that your guide scope focal length is set properly in PHD2 in the scope setup window.
Then image away.
OK, the Mach2 arrived Friday and I took a trip out to the observatory last night. 

Had been able to update my ASCOM/AP Driver/PHD2/SGP software and driver stack.  TheSkyX connects.  APCC Pro was set up and functioning.

No modeling or other fancy stuff yet.

Here is a segment of guiding after the sequence completed and there weren't any dithers for a while.
