Totals per group over 50 topics of unique relevant retrieved.
Here, unique relevant document is defined using the following criteria:
   1. set of runs consists of judged runs from both Common Core and
	News tracks (since both contributed to the same pools). A "mixture"
	document is a relevant document that only one group
	retrieved, but that group retrieved the document in both judged
	News track and judged Core track runs.
   2. a document retrieved by multiple runs of the same group
	is counted as unique as long as no other group retrieved it
   3. consider only the top 150 ranks as the retrieved set
   4. only judged runs are used in the computation
   5. total is over all topics and all judged runs of the group
