I haven't looked at the code, so I don't know the details of the
algorithm that is actually used, but from what Ezio said your example
is *not* correct.  The numbers in parenthesis are the number of issues
opened/closed in the past week that are *still* open or closed.  So open
would certainly not be +2.  I'm not sure if it would be +0 or -1 without
looking at the code.

I agree that having the delta against open from the previous week would
be the most helpful.
