'World Peace and Stability' Index

World Peace and Stability Index is a measure of stability and/or volatility of the world on a particular day. It is calculated as the "Number of times CNN news channel repeats a tape". Zero indicates a turbulent world with a lot of disturbing events going on in various parts. A high value signifies there're not many major events and the world is mostly peaceful.

Basis: CNN is (in)famous for telecasting the same 5-minute recording more than hundred times a day. If, on a particular day, even CNN is unable to repeat the same tape twice, it would mean that there must be so many ghastly activities going on in various parts of the world. They're probably caught up with only fresh tapes from all over.
