How does system double perrier work in golf scoring?

Answer 1

Guidelines on Handicap Calculation

Competition Format: The famous Japanese "Double Perrier" system to determine the winner.

1. Select 12 holes for calculation of handicap. This may be done by a lottery after the play.

2. Handicap (HD) is 36 or less and determined by the following equations:

HD is the summation of the each selected 12 hole's handicap (HDeach) multiplied by the ratio of total sum of par of the course against the total par of the selected 12 holes and further multiplied by 0.9 (handicap ratio) or 36 whichever the small.

i.e.,

HD=MIN(0.9*(sum of HDeach *(sum of par of the course/sum of par of the selected 12 holes), 36)

2.1 HDeach

handicap of each selected hole (HDeach) is Zero or (HDeach-calc) whichever the larger.

i.e., HDeach=MAX ( HDeach-calc, 0 )

This means HDeach is always 0 or more. If you hit eagle or birdie at the hole, you will get a advantage (never make handicap minus)

2.2 HDeach-calc

HDeach-calc is the par number of the hole or (the score of the hole minus the par number of the hole) whichever the smaller.

HDeach-calc=MIN( par of the hole, (score -par of the hole) )

This means HDeach-calc is always equal to or less than the par number of the hole. If you hit more than double of the par number at a hole, the part of your score more than double of the par number of the hole is not taken into account the handicap and disadvantage of you. Do not hit too much.

3. Advantages of winners

For honor of the winners, in addition to the calculation as described in paragraph 2 above;

The handicap of the winner of the last session is HD-3, and

The handicap of the winners of the past sessions is HD-2.
