Tournament formats

"Compekun" offers the following four tournament formats:

  1. Double Peoria
  2. Double Peoria (Front 9)
  3. Under Handicap
  4. Scratch

1. Double Peoria

Double Peoria, also known as New Peoria, is widely used, mainly in Japan, because it allows for easy handicap calculation. However, it is not stipulated in the Rules of Golf, nor is it established by official golf organizations such as the R&A, USGA, or JGA. There are also multiple calculation methods.

"Compekun" uses the following method, which is considered the most common.

■Hidden Holes
12 holes are selected from 18 holes (6 holes each for the first 9 holes and the second 9 holes so that the total par is 48)
■Handicap Calculation Formula
(Score of Hidden Holes × 3 ÷ 2 - [Total Par of 18 Holes]) × 80% = Handicap
  • Sometimes "× 3 ÷ 2" is replaced with "× 1.5". The calculation result is the same.

  • In some cases, an upper limit is set for the score of the hidden holes based on the value of Par. For example, the "double par cut" setting uses a multiple of Par as the upper limit. Not setting an upper limit is considered advantageous for beginners.

  • In some cases, an upper limit is set for the handicap. The common limit is "36". Setting it to unlimited is considered advantageous for beginners.

Ranking is determined by the net score, which is calculated by subtracting the handicap from the playing score (gross score). "Compekun" allows you to define how rankings are determined in case of a tie in net scores. You can choose from the following six options:

  • Prioritize the player with the lower handicap
  • Prioritize the older player
  • Prioritize the female player
  • Countback (matching scores from the later holes)
  • Matching Scorecard
  • Matching Scorecard (KGA)

For details, please refer to *Ranking Determination Method in Case of a Tie**.

2. Double Peoria (Front 9)

This is a method used in tournaments commonly known as "half-compe (competitions)". The Double Peoria rules are applied to the first 9 holes for scoring. The advantage is that scoring can be completed before the end of 18 holes, allowing for immediate distribution of tournament prizes after play.

"Compekun" offers the following methods:

■Hidden Holes
12 holes are selected for every 18 holes (6 holes each for the first 9 holes and the second 9 holes so that the total par is 48)
■Handicap Calculation Formula
(Score of Hidden Holes × 3 ÷ 2 - [Total Par of the First 9 Holes]) × 80% = Handicap
*This differs from the regular Double Peoria only in the value of the par subtracted in the handicap calculation formula.

In tournaments with multiple groups where the starting course is divided by group (e.g., OUT/IN starts separately), there may be an unfairness due to competing on courses of different difficulty levels. However, this method is sometimes adopted because the advantage of being able to compete casually outweighs this disadvantage.

3. Under Handicap

This is a method of tournament using the handicap that each player declares in advance. Rankings are determined by the net score, which is calculated by subtracting the handicap from the gross score.

There are several ways to obtain a handicap, including through your golf club or online services. Please see below for details.

4. Scratch

This method does not use handicaps; rankings are determined solely by playing score (gross score). Professional tournaments use the scratch method. It is suitable for tournaments between players with small skill differences.
