I don't seem to have the sendsize*debug file from that test so I just ran it 
again my amdump.1 log from this test has the same "missing estimate" messages.  
Here is the content: 

sendsize: debug 1 pid 33302 ruid 80 euid 80: start at Thu Jul 15 13:17:20 2004
sendsize: version 2.4.4p2

And what does /tmp/amanda/sendsize*debug on mike have to say?
