Time to make its history maybe.  Amanda keeps track of the compression 
achieved on a given DLE, and uses that historical figure to estimate the 
new backup being contemplated.  And without any history, probably assumes 
a zero for compression effectiveness.  Here, for relatively stable DLE's, 
it can get very very accurate after a few weeks.
