|Viking Star, Cost to Cruise December 2013|
And I have to admit I found some errors in the spread-sheet. Largest was that back in March I had entered our fuel cost twice! Backing out that $653 helps a little. And I found there is a difference in how the Average formula treats a blank cell vs. one that has a '0' in it. In this view I have gone back and made sure all the '-' cells actually contain a '0', and are not just blank. So, you might see some larger then expected changes in a few of the rolling averages.
