I am going in circles on this. Perhaps its simpler than I am making it.

3 rows are added to a file most days. Lets say, to give a perspective, that somewhere around 300 days/year there are 3 records added. Never 4, never 2. Its 3 or none. I want 3 rows for every week of the year, in descending order, but only the last active day in each week. Normally it is day 7, sometimes day 6, rarely day 5.
