"*Always compare against the last valid session event, not against one(s) that just got dropped*", is one of the requirements (https://issues.apache.org/jira/browse/MADLIB-1002).
I think the LAG() functions used in the query always end up finding the difference between the time stamps of the current row and the previous row. It should instead be comparing with the last row that was part of the session, and not the last row that was ignored due to the min_time constraint.
