How is the 18Birdies Handicap different from the World Handicap & USGA Handicap?
The 18Birdies Handicap uses similar inputs to a USGA® handicap in that both rely upon use of the Course Rating™ and Slope Rating® for a given golf course. The handicaps differ as follows:
| 18Birdies | USGA® |
| Will calculate a handicap for as few as 1 - 5 rounds of golf played. | Will only calculate a handicap when at least 5 rounds have been played. |
| No maximum handicap. | Maximum handicap of 54 |
| No adjustment to your handicap for unusually bad scores on a hole or bad weather. | Accounts for unusually bad holes or bad weather with Equitable Stroke Control™ |
| No multiplication adjustment for your handicap. | Multiplies your score by 0.96 to determine your handicap. |
| Will use a score from 9 holes to calculate your handicap (scored multiplied by 2) | Combines 9 holes from different courses or different rounds to get one 18-hole score. |
