Yes, it may be better, the question is, what is "clever setting".
I don't know enough about e00 and in file i have here is no 
threshold (BWT, where can I find e00 format description?).

If you have threshold for e00, what that means?
If it means that the file contains unclosed areas with 
gaps < thresh and does not contain lines with vertices
in distance < thresh it is of course best to use that. 
But I guess that's not thrue, at least for files generated by 
Arc/Info - I don't know.

If you have more files with supplied threshold, could you
test to build with that threshold and threshold=0, and tell us
the results?
