Can you provide a tbwx along with the expected result from the data in it?
You need to use the Advanced option on the Compute Using to set the order to be used by the table calculation to be the opposite of the order used in the view (by default it will be based on the order of the view).

Hi Alex and Richard,
Thanks for your input, however I answered my own question soon after I posted it.
I sorted the data by date, then created the following calculated field, which I placed next to my daily total column
TOTAL(SUM([Times Launched])) - RUNNING_SUM(SUM([Times Launched]))
As can be seen, the first line shows the cumulative total/grand total, then subsequent lines get closer to zero. Below is a screenshot.
