Not incorrect, just misinterpreted.
The problem is that the 7818 Watt-hour number is a daily amount, just averaged over a one-week period. The key is:
5. Watt hours - column 1 x column 2 x (column 3 divided by 7) = watt hours
The "divided by seven" bit gives us average watt-hours per day.
The total for a month would be 235 kWhr. Truth be known, 7.8 kWhr per day is very, very good! Wikianswers suggests that the average US household consumes 29.2 kWhr per day.
