Bob,
I will set those parameters to zero. Here are two log files (Autofocus and ACP) which illustrate the "skipping pointing update" issue. The Autofocus log shows that autofocus started with a slew to the autofocus position and ended at 6:21:12 . The ACP log starts at 6:21:18 with a slew 2 seconds later to the target. At 6:21:31 "skipping pointing action, target close enough" message appears even though the last position was autofocus, not the target.
