Thank you very much, this explains it perfectly. I had been coming to the conclusion that the shared data must be what accounts for the "missing" space, but previously my thinking/expectation was that it would be "charged" against the snapshot in which the shared data first appeared. Doing that would probably bring its own complications too though I suppose, so I can see why the decision was made to lump it all together in the "usedbysnapshots" figure rather than complicate the zfs command output further.
It does lead to another question though: is there a way to see how much data is shared between any two given snapshots?
