Yes,  programs like Timelab and Stable32 are definitely the way to go for 
post-processing and analyzing your data in depth.   Lady Heather is more of a 
real-time monitoring and data acquisition program.   

The sensitivity of ADEV to data hiccups can be a good thing.  If your ADEV data 
goes to crap you know you have a problem and need to examine the data in more 
depth to find out why.   You can go in and remove / fixup the outliers to get a 
better understanding of the typical device performance  but leaving in the 
"zingers" tells you what the device is truly doing.

Maybe we have hyped ADEV too much on this list. This rant is especially 
addressed at several LH and NTP authors who think analyzing clock data and 
making ADEV plots is just something you blindly code or script or automate, as 
if working with clock measurement data was as pure as mathematics.
