Handicap Calculation Overview
The handicapping feature of Handicap System calculates three types of handicaps for 9 or 18 holes:
You are not locked into just one calculation mode. You can switch calculation modes at any time. For example, your club may issue USGA handicaps to its membership, but for local tournaments use a custom handicap that is based only on scores shot in tournament play. Note that you can have only one Handicap Mode selected for a Roster at any given moment. However, you may switch between Handicap Modes at any time for a Roster. These modes do not affect any of your posted data. Only the calculation used changes when you change the Handicap Mode.
Official handicap – what makes a golf handicap an official golf handicap?
Some folks assume some software or a service provides an "official" USGA Handicap. However, it is the issuing organization which makes a handicap official or not. Please see Official handicap – what makes a golf handicap an official golf handicap?
USGA Handicap Revision Schedule
Beginning in 2012 the USGA established the National Revision Schedule. The National Revision Schedule requires all domestic golf clubs to revise Indexes on the 1st and the 15th of each month during the calendar year.
Thus, those calculating a USGA handicap should use the National Revision Schedule. All scores played at a course or in a region where the "active season" was in effect must be posted. The governing golf association for a region designates the dates for the active season and inactive season.
RCGA Handicap Revision Schedule
The RCGA does not have a Factor revision schedule. Each player's Factor is revised after each round played and posted. It is therefore important that scores be posted before the next round is played.
Custom Handicap Revision Schedule
With a Custom handicap, it is up to your organization to set its own revision schedule.
