Biggest Loser, Engineer Style

Ben paid thirty cents to his coworker who lost 3.5 percent of her weight last week. Ben lost 3.2 percent. Why? Motivation. That and his WSDOT office is on week two of a biggest loser challenge. And maybe it's just me, but I thought that the set-up screamed math nerd. Judge for youselves:

Day one: Weigh in. Report weight to spreadsheet supervisor.
Day seven: Weigh in. Calculate weight loss percentage to the nearest tenth of a percent (with the following formula: original weight minus current weight divided by original weight). Report percent change to spreadsheet supervisor/creator. Pay 10 cents per tenth of one percent difference between your percent change and the winner's percent change. Repeat weigh-in and calculations every week.

So simple! (I say with zero tenths of a percent of sincerity.)

You're so simple! (My sweet spouse responds.)

Your cut downs are so simple! (I say a couple days later--George Costanza style.)
