Again you could merge all pwrite calls into one XFS_IO_PROG command
and use -W to sync.

At this point there are many "od" outputs, so it would be convenient
to at least echo some information so if there is a problem in the
output we can easily identify what caused it.
For example
echo "2. Cloning range starts at the middle of a hole"
