We've all watched football games and groaned and roared at the really big hits. But have you ever wondered which hit is the biggest?

The Pounder Index^TM, specifically developed by McDonald's^® and sponsored by the Double Quarter Pounder^® with Cheese, is the first statistic ever to translate the impact of a football hit into a rating on a 10-point scale.

The exact mathematic formula for generating the Pounder Index^TM, as developed by the sports statistics gurus STATS, is an industry secret. But the basics go like this:

• Start with a clean hit. No penalties or cheap shots allowed.
• Add the weight times speed of all intersecting players. A three-man pile up would look like this: (M=Mass, A=acceleration)
  
  
  
• Adjust for angle of attack, giving the highest value to head-on impact. The result is the Pounder Index^TM.
  
  

So when you're ready for some big-time football, grab yourself a Double Quarter Pounder^® with Cheese, tune into The NFL on CBS, and sink your teeth into the biggest hits of the season, courtesy of the Pounder Index^TM.
