That depends on the changes in the Openoffice package.
Lets see...
Update from 1.9.125 to 2.0.0: 10 Mbyte.
Update from 1.99.3 to 2.0.0: 4 Mbyte.
On avarage deltas are about 5%-10% of the rpm size.

Well, the deltas are between two version. So if you want them to
work with a distribution that changes a lot like fedora (i.e.
if you don't do just maintenance updates) you have two possibilities:
- delete all of th old deltas and create deltas between the old
versions and the current one. The drawback is that you have to keep
the old rpms around for delta generation (they don't need to be in
the repo, though) and the mirrors have to fetch all the new
deltas.
- create only one delta between the last version and the new one.
This creates a chain of deltas, so the mirrors only have to pick
up one delta. The disadvantage is that you have to use a special
server that combines the deltas on the fly or, if you don't want
that, clients that have an old version must fetch more than one
delta and combine them.
In any case, keeping deltas against the last 10 versions roughly
doubles the repo size.
Cheers,
Michael.
