There appears to be a bug in calculating the ranking of users that leaves gaps in the sequence.
As an example, see http://scn.sap.com/reputation.jspa?username=jamie.wiseman#viewID=leaders
and scan down the list. Why is there nobody listed at rank 128?
I have seen cases where there has been a tie for the number of points and multiple people
had the same rank with an appropriate number of gaps above the ranking. But that isn't
the case here.
