edso posted a new comment:
@gcc the formula to calculate a proper blocksize was changed in
duplicity v3.0.3

the man page reads now
"
--max-blocksize number

limits the maximum size of the blocks examined for changes during the
diff process.

By default the integer square root of file length is used as the
librsync block size. Minimum being 512 byte with no maximum unless
--max-blocksize is supplied. Block size is rounded up to the nearest 512
byte boundary.

If you specify a larger max_blocksize, your difftar files will be
larger, but your sigtar files will be smaller. If you specify a smaller
max_blocksize, the reverse occurs.

The --max-blocksize option should be in multiples of 512.

Max blocksize defaults to not supplied.
