In Response To: Proposed World Ranking System (Keene)

Keene,

I initially weighted the years 5-4-3-2-1, but Igor (a math professor) recommended SQRT(5), SQRT(4), SQRT(3), SQRT(2), SQRT(1).

After I follow your advice and add more people, it's easy to play with the spreadsheet and try different numbers. That's the wonderful value of spreadsheets. [interesting sidebar: the co-inventor of the spreadsheet was a classmate of mine at MIT]
