text: In September 2018, the renamed GolfRSA Handicap System adopted the USGA Course and Slope Rating system. This necessitated a few additional changes (e.g. playing handicap and differential calculations), but the system retained all other features (e.g. Adjusted Gross and no daily course rating adjustment). The playing handicap under the GolfRSA system includes the difference between the Course Rating and Par.
  In October 2019, further changes were made which brought the GolfRSA Handicap System further into line with the upcoming World Handicap System. The changes introduced included reducing the number of differentials used in handicap calculations from 10 down to 8, net double bogey as the maximum score per hole, reducing the minimum number of valid 18-hole scores required for handicapping to three, and exceptional scoring reductions.
  Argentinian Handicap System
  The Argentine Golf Association (AAG) handicapping system is a relatively simple one, using only a course rating, without slope. New handicaps require the submission of scorecards from five 18-hole rounds (or ten 9-hole rounds). An initial handicap of 25 is normally used as a starting point, which is then adjusted based on the submitted scores. Handicaps are updated once every month, with current handicaps generated from a lookup table using the average of the best eight differentials from the last 16 rounds. Golfers simply use their exact handicap for playing purposes.
  Other systems
  For the handicapping of golfers who are ineligible for an official handicap, some system options are available:
