New World Handicap System (WHS)

Laguna Golf Phuket now uses the new World Handicap System (WHS) to manage member handicaps.


All members who keep a home handicap at Laguna Golf Phuket will already have had their USGA handicap index converted to the new (WHS) handicap index through our existing MyScorecard system.


Effective from July, the Club will update member handicaps weekly, these updates will be posted on the notice board EVERY Friday by 12pm, in the meantime, the Club will continue posting handicap updates on the 1st & 15th of each month.


Although the WHS system works on the premise of daily handicap updates and recalculations after each submitted score, the submission, inputting of scores and printing out of daily handicap updates is operationally impractical for the Club at this time. The Club will use the latest handicap update for all club competitions.


We encourage all members to embrace the new WHS system, members can easily submit their own scores on the day of play or next available day online by logging into their own handicap account at or by downloading the MyScorecard app on their smartphone to get an immediate update of their handicap index.


Key changes between the WHS and USGA handicapping systems

  • WHS system recalculates a player’s handicap index after each round is submitted and recorded into the system ready for the next day’s play.
  • Modified Handicap calculation formula:

Course Handicap = Handicap Index x (Slope Rating/113) + (Course Rating – par) This will see greater variances in course handicaps, when playing from different sets of Tee boxes compared to the USGA system.

  • WHS system uses 8 of your recent 20 scores to calculate your handicap index opposed to 10 of your past 20 scores with the USGA system.
  • Maximum net double bogey is the maximum hole score permitted for handicap calculations with the WHS system.

USGA system used Equitable Stroke Control (ESC) to cap the maximum score on any hole based on a sliding scale depending on your course handicap (eg. Course handicap 10-19 could take a maximum score of 7 on any hole).

  • Playing Conditions Calculation (PCC)

This new feature adjusts how your score impacts your index based on the average of all scores posted on the course on that day. The WHS algorithm accounts for this to keep the score from negatively affecting your index.

  • Maximum Handicap Index raised to 0 for both men & women.
