PEC in the LX200GPS scopes can be done in Polar or AltAz.
When Polar, the Meade PEC "model" is normally quite acceptable,
but as you are in the Southern Hemisphere,
the data has to be inverted after training before it will work correctly.
In AltAz, i wouldnt bother as the PEC code Meade uses is severely broken.
That said, when polar, PEMPro will get you a true "Periodic Error" model, and hence will be better than the std Meade Model, which includes all the non periodic errors as well.
How much better will depend on how bad your original PE is ( the Meades can vary quite a bit ).
Goto functions perfectly well when polar, but its accuracy really depends on having a good polar alignment. Meade have a polar 2 star routine, but this doesnt always work properly, and should be avoided for permanent setups,
Do a good drift align, then just do a fake manual one star align and you are away.
