So was the wait worth it?
I tested the periodic error of my new mount with PemPro. ( I did not order the encoders)

Native without PEC:

+1.5/-1.4 arc seconds periodic error. 

0.42 RMS arc seconds.

With the factory PEC

+0/-0 arc seconds periodic error.

0.34 RMS arc seconds.

This is with no encoders. The PEC enabled curve was essentially a straight line with little variations due to seeing.
What can you say besides, Wow!
