What's your sample interval?  If you allowed the program to automatically
sense the incoming data rate from the counter, did it have enough time to
settle down before you pressed 'Start Measurement'?  (If you would like to
send a short .tim file to me at john (at) miles.io I'll have a look at it.)

How about the frequency difference view ('f' key)?  Does that advance at one
point per second as expected?   Some confusion may be associated with the
ADEV graph's X-axis itself -- it is not a measure of elapsed time, and the
graph does not normally advance with each incoming data point.
