Hope GST 101 was helpful. If you have questions, please leave a comment and I will get back to you.
For GST 102, we will look at two putting statistics you may hear when watching golf broadcasts or listening on the radio:Total Putting and Putting Average.
To determine Total Putting, the PGA TOUR looks at six different putting statistics: putting from 3-5 feet, putting from 5-10 feet, putting from 10-15 feet, putting from 15-20 feet, putting from 20-25 feet and three putt avoidance from greater than 25 feet.
For the first five of those categories, the PGA TOUR would define each category as "for all holes where putting distance was determined with a laser, the percent of putts made when the ball is greater than __ feet and less than or equal to __ feet from the hole. In order to be ranked, a minimum of ten attempts must be made."
For three putt avoidance from greater than 25 feet, the PGA TOUR looks at "those holes where putting distance was determined with a laser, the percent of time 3 or more putts were taken for a hole (total 3-putts, 4-putts, etc./total holes played) when the initial putt is greater than or equal to 25 feet from the hole. NOTE: In order to be ranked in this YTD statistic, a minimum of ten attempts must be made."
To then compute the figures and arrive at the Total Putting number "each statistic is given a numerical weighting based on the frequency of putts attempted from each distance. The players rank in each of the statistics used is multiplied by the corresponding weigh factor, totalled, and divided by the number of statistics used to produce the Total Putting Value."
For the 2012 season, Luke Donald was far and away the leader in Total Putting with a figure of 16.8. The next best on the Tour was Brandt Snedeker with a figure of 61.8.
Putting Average is a completely different measurement. It is defined by the PGA TOUR as "the average number of putts per green in regulation. By using greens hit in regulation, we are able to eliminate the effects of chipping close and one-putting in the computation." Another way to think of Putting Average is Greens In Regulation Putts/Greens in Regulation.
Example:in 2012, Jonas Blixt took 1,378 GIR Putts after he hit 802 Greens in Regulation (he was ranked T 134th in GIR) for an average of 1.718. Brandt Snedeker (no surprise there) was 2nd in Putting Average at 1.725.
Remember in GST 101(http://bit.ly/UNetNm) we saw that Boo Weekley was number 1 in Balll Striking and number 1 in Total Driving . If we look at his numbers in Total Putting and Putting Average, we will see an altogether different scenario. In Total Putting for 2012, Weekley ranked 189th of 191 players ranked. In Putting Average, Weekley ranked 187th of 191 players ranked. Contrast Weekley with Luke Donald. Donald was 112th in Ball Striking and 121st in Total Driving but was number 1 in Total Putting and was number 14 in Putting Average.
