isn't a clock deviation of 0.00001% too small?

I just wanted to try and swtiched off my reclock to see the data madvr was getting. Clock deviation was varying between 0.00003 to 0.00009 till at something like 20 mins in the movie, it got stuck at 0.00001% (going to 0.00002% from time to time).
Other data was:
Display 23.99999Hz
Composition rate:24.000Hz
Movie 23.976 fps
1 frame repeated every 41.76 secs

Were you playing without sound? You need to have an active audio renderer going, otherwise that's what I usually get.

No no, it was with sound.
I uninstalled GeForce Experience, and repeated the test, and this time it gave me -0.00003% , still low i guess
