Poll: how to report # of docs in index over time

Hello,

Quick poll for those who have an opinion about what index size monitoring should report in terms of the number of documents in the index.

Poll: http://blog.sematext.com/2012/02/13/poll-solr-index-size-monitoring/

For example, imagine that in some 5-minute time period (say 10:00 AM to 10:05 AM) we check the index 5 times (in reality we do it much for frequently) and each time we do that we find the index has a different number of documents in it: 10, 15, 20, 25, and finally 30 documents.  Now imagine this data as a graph showing the number of indexed document over time, but with the smallest  time period shown being a 5 minutes interval.

Given the above example,how many documents should this graph report for the 10:00 – 10:05 AM period?
Should it show the minimum – 10?  Average – 20?  Mean – 20?  Maximum -30?  Minimum, average, and maximum – 10, 20, 30?   Something else? 

Thanks!
