This calculation also looks to begin at midnight. I don't think we can assume an even spending pattern throughout the day. You will have to take into account multiple days and weekends to test to see if there is a change in buying behavior by hour or day before you can make these assumptions. And then there are press events most likely planned that could accelerate the buying. Or another event that could slow buying.
