What is short, medium, and long?

Radio astronomers use H-masers.  Can I assume that they are mid-term and that 
H-masers are better than Rb (at mid-term)?

Does the classic ADEV graph contain all the information, or is it making an 
assumption that is valid in most cases that allows it to compress/hide lots 
of information that is interesting for only a few obscure types of 

These are my opinions.  I hate spam.
