John,
I gave you some misinformation.....
1. The counters on the motors give a Dec position and an RA position based on their "zero" position - usually set at the home position.
2. When in the home position (pointing at SCP c'weights down) the Dec counter shows "-90 deg" and the RA counter "180 deg ( - the azimuth reading for the meridian.)
3. The RA shown is six hours above the LST.
4. When you slew to a target, the RA and Dec increment to the target settings (and agree with CdC)
5. When you re-park to home position - the counters return to the readings as per 2 above and park RA is incremented to LST plus 6 hours.
See the attached images.
Read through the EQMod manual (in the EQMod folder) for details on how it handles GOTO accuracy - based on triangles of known points.
