Hi Robert,
I've just had a go with the difference accuracies. In general, with accuracies 
1, 5, and 10, the results seem to vary by less than 1ms.
Given that repeated measurements of latency seem to vary by more than 1ms, I'm 
not sure if there's any need for an accuracy of less than 1ms.

Thank you david for testing.
Have you tried different accuracies?
"1" means 44-samples and 10 4-sample precision (at a 44.1 kHz sample-rate).
Click-tracks might not be so ideal, especially at a multiple of 60.
However, My recent tests did all yield a proper result. I've tested
with click-track, flamenco-style (included in the plug-in) and chirp.
Recording device is stereo mix (fairly noisy, with strong DC-offset).
The latency average is 89 ms and varies by about +/-4 ms.
I know that there are sometimes ironious return-values (i.e. high
ones). I simply ignore them and test anew, either with a new selection
or a new recording.
There's currently no microphone plugged into my computer, so I can't
tell about such measurements.
I really do appreciate your feed back.
