I remembered reading a post about this a couple of months back. This post by Jeff Bonwick confirms that the dedupratio is calculated only on the data that you've attempted to deduplicate, i.e. only the data written whilst dedup is turned on - http://mail.opensolaris.org/pipermail/zfs-discuss/2009-December/034721.html .
Ah, I was on the right track then with the DDT then :) guess most people have it turned on/off from the begining until BP rewrite to ensure everything is deduplicated(which is probably a good idea).
