T,

"The Wilks formula like its predecessors, the O'Carroll and Schwartz formulas, were set up to address the imbalances whereby lighter lifters tend to have a greater power-to-weight ratio ... lighter lifters tending to lift more weight in relation to their own bodyweight. This occurs for a number of reasons relating to simple physics, the nature of the makeup and limitations of the human skeletal and muscular system and, the shorter leverages of smaller people. This phenomenon can be seen by looking at the current men's senior world powerlifting records. http://www.powerlifting-ipf.com/Records.44.0.html Note the totals section and that lighter lifters below 100 kg bodyweight achieve totals in excess of ten times bodyweight whereas heavier lifters do not. The Wilks system is primarily a handicapping process that provides an adjusted statistical method to compare all lifters of varying classes and groups on an equal standing and makes allowances for the disparities. Wilks charts and a calculator are freely available on the website of the International Powerlifting Federation (IPF)."

Great find AJ!

It is fun to read that the Wilks formula is not a 'Make the little guy look cool' formula, as some believe it to be. Rather, to the contrary, it disadvantages the lighter lifter in the (### x BW) formula - and is designed to be a true leveler of the playing field.

The Equinox Open "Best Lifter" awards goes by the wilks formula and went to:

Susan Stephens - 366.3 @ 55.7 Kg BW

andNun Amen-Ra - 440.18 @ 81.05 Kg BW

For those interested in the details, the formula for the Wilkes coefficient is here:

http://en.wikipedia.org/wiki/Wilks_Coefficient

It's a reciprocal polynomial.

Note that the text AJ excerpted is from the same site.

I'm guessing the various coefficients were arrived at emprically, rather than from first principles.
