That's very encouraging - thank you! I imported the musicXML file into
Denemo and corrected the mistake in bar 6 where a dotted rhythm is
doubled in duration and a note missing. Then I spent 4 mins 10 seconds
splitting it into movements and putting in the Upbeat command which was
missing from the second movement. (And moving the time signatures that
are consistently placed at the end of the bar in subsequent part instead
of the beginning - I've filed a bug report for this).

The result is the attached. I haven't proof-read it but at a glance it
looks ok. At 4 mins (OCR) + 4 mins (editing in Denemo) this would
compare favorably with the second attached version which I entered via
Denemo.
That took 52 mins, which is a clear winner even allowing that the 52
minutes includes entering the figured bass (which I did by playing the
notes corresponding to the figures, so I could hear any errors) and
creating the title page with the incipit, adjusting the page breaks for
both score and parts and ensuring that repeats started at line starts.

This confirms what people have said elsewhere - that Audiveris lags
behind SharpEye/PhotoScore (these two are the same OCR with different
front ends/marketing as I understand it). Perhaps the long-awaited
re-write of Audiveris may change that?
