PGA and Statistics

Came across this interesting collection of papers on golf statistics.
The Wharton paper on Loss Aversion is very interesting. Golf pros put better for par than for birdie. A bias that cost the best players 1.2m in prize money a year.
Pros also make 99.2% of the puts of 3 feet or less, pros make less than 50% of puts longer than 8 feet.
