At what tau values, though?  The idea behind ADEV is that it goes lower the
longer you run.  When you first launch the program, you only have a
short-term history to observe.

The graph-recentering behavior can be extremely confusing because it gives
the appearance of jumps that aren't really happening.  Try running with /m=4
to compress the graph height 4x and see if you still observe unexpected
initial behavior.  I haven't seen anything happening myself that I couldn't
eventually put down to recentering.
