I don't know.

Are you by any chance using exclusion lists in tar ?
calcsize does not (yet) support exclusion lists .
It's something I was going to do in my spare time (fixing calcsize to
handle exclusion lists), but between work, family and sheer exhaustion I
haven't had much spare time in the last 2 months ;( ..
At any rate,
Im gonna have a look at my own tests on calcsize, I had figured out a way
to run the various estimate programs (ufsdump, gnutar and calcsize) from
the command line and could compare the results.
If you happen to have a debug file lying around from the previous runs (the
tar iso calcsize extimates) you can find the exact tar command in there.
Could you do me a favor and run the tar - estimate commands by hand, as
well as the calcsize estimates and let me know the results.
