Observing Summary:

At around 3:00 the focus froze on me. Couldn't use the
handpaddle (at any speed) or the TCS to unfreeze it. It drifted
slowly down to 5300 (I had it set to 5350) thenslowly started 
creeping back up to 5320. At 4:30 the focus jumped to over 9000. 
I was able to move it at that point back to 5350. Didn't lose
time over this. No other issues
