You certainly did.

I was just objecting to the fact that Davina said that Networker
by design cannot do concurrent reads from disk as this limitation
was removed in 7.3 up. Try to recover two or more savesets from
the same AFTD and you will see them both happening at the
same time.
I did not claim that NW would do the cloning in parallell.

Sorry for the misunderstanding
