Statement from the Technical Provider of WWGR Inc.
Last week, we issued some projections which showed Ariya Jutanugarn taking over the No. 1 spot in the Rolex Women’s World Golf Rankings based on player finishes at the LPGA’s 2017 ShopRite LPGA Classic which concluded yesterday (Sunday, June 4). However, when official rankings were run this morning (Monday, June 5), we discovered a bug in the projection tool.
When running the projections, the tool used the date on which the projections were run, rather than the date when the rankings would be released. Thus when projections were run last week, they included the 2015 Manulife LPGA Classic in the event count for both Lydia Ko (51 events) and Ariya Jutanugarn (58 events). When the Rankings were run today, that event correctly dropped from the Rankings’ 104-week cycle and reduced the total number of events for both players by one (Ko – 50 events; Jutanugarn 57 events) which resulted in average world ranking points of 8.37 for Ko and 8.36 for Jutanugarn. So Ko maintains the No. 1 position by a .01 point margin.
We are working to correct the problem within the projection tool and we apologize for the error in last week’s projections.
