When the row size of your highest resolution RRA is 1 week, then your
database will contain a value for the end of each week.

That value will have an epoch timestamp of N x 604800.
With N being an integer.

The closest N times 604800 may have been at a wednesday for the start
of your graph. You want to have the agility to choose the starting day.
Giving the database a 1 day resolution will help you.
