I wonder what the counter is based on, though. If it's the JB3's internal clock, or the # of samples it's received from the external source at a given samplerate.
Regardless, I agree it won't affect the sound of the recording. I'm just curious if it's indicative of a larger problem. I will test tonight to see if I can reproduce it w/ and w/o the UA-5, and with the UA-5 and a different JB3.
