CAPÍTULO IV

19 - redução de HANDICAP INDEX baseada em resultados exepcionais de campeonatos


Aplicar-se-á a regra 10-3 do Sistema de Handicap da USGA 2008-2011
* A tradução desta regra será anexada a este regulamento e enviada aos clubes assim que concluída

10-3. Reduction of Handicap Index Based on Exceptional Tournament Scores
Using the definition of a
tournament score (see tournament score and Decisions 10-3/1 through 10-3/6), the committee (preferably the Handicap Committee in consultation with the committee in charge of the competition) must determine in advance whether a score is to be designated as a tournament score that is to be identified by the letter "T" when posted (e.g., 82T). These scores are often referred to as "T-Scores" as in Section 10-3c.
a. Procedure

The following procedure must be used as an alternate calculation of a
> Handicap Index for players with two or more eligible tournament scores. A player's Handicap Index may be reduced under this procedure when a player has a minimum of two eligible tournament score differentials that are at least 3.0 better than the player's Handicap Index calculated under Section 10-2.
The
Handicap Committee or handicap computation service must apply the following steps to determine if there is a reduction in Handicap Index calculated under Section 10-2
b. Steps

Example:
A player with a Handicap Index of 17.3 has three eligible tournament scores, an 82T, 83T and 85T. Two of these eligible tournament scores, an 82T and
83T, produce the lowest
tournament score differentials. They were made on a course with a USGA Course Rating of 70.6 and a Slope Rating of 130
Step 1:
Calculate tournament score differentials by subtracting the USGA Course Rating from each eligible tournament score; multiply the result by 113, and divide by the Slope Rating for each course played. Select the two lowest eligible tournament score differentials.

Step 2: Subtract the second lowest differential from the Handicap Index under Section 10-2. Continue with the next step if the result is 3.0 or greater.

 

 

 

 

 

Step 3: Average the two lowest tournament score differentials.

2 best T-score Differential average of
differentials 2 lowest T-scores

Step 4:
Subtract that average from the player's Handicap Index.

Step 5: Using the number (rounded to the nearest tenths place (7.0) from step 4 and the total number of tournament scores in the player's record (3), use the Handicap Reduction Table to determine the amount the player's Handicap Index is to be reduced.
Step 6:
Subtract the table value from the player's Handicap Index. The result of that subtraction will be the player's reduced Handicap Index, provided that it is at least 1.0 less than the Handicap Index based on the formula in Section 10-2. The reduced Handicap Index is to be identified with the letter R when displayed in handicap reports or on the computer screen, e.g., 12.3R.
Step 6:
Subtract the table value from the player's Handicap Index. The result of that subtraction will be the player's reduced Handicap Index, provided that it is at least 1.0 less than the Handicap Index based on the formula in Section 10-2. The reduced Handicap Index is to be identified with the letter R when displayed in handicap reports or on the computer screen, e.g., 12.3R.

 


 

Example:
Value from Handicap Reduction Table 5.0

Handicap Index
-- Table Value: 17.3 - 5.0 = 12.3
Reduced
Handicap Index: 12.3R
c. Counting Tournament Scores

(i) T-Score Counter -- The number of
eligible tournament scores will be counted on a revolving twelve-month basis. In order to keep track of the counter, but not save every T-Score, a counter for each month is needed. The T-Score counter will contain the sum of the latest twelve monthly counters plus any T-Scores older than one year that are a part of the twenty score history. The monthly
counter will increase based on the date a score is processed, not the date of the score.
(ii) Best T-Score File -- Up to the best six
eligible tournament scores are saved in a "Best T-Score File," separate from the player's handicap record of the latest 20 scores.
(iii) Adding T-Scores -- When a new
tournament score is posted, it becomes part of the player's normal handicap record as a score and Handicap Differential. If the "Best T-Score File" has fewer than six eligible tournament scores, the new T-Score is added to that file. If the file already has six T-Scores, the new T-Score, if better than any T-Score in the file, is added to the file and the worst T-Score in the file is deleted, regardless of the date of the T-Score.
(iv) Discarding Old T-Scores -- At each handicap revision, each
T-Score in the "Best T-Score File" is checked to see if the score is older than one year and no longer part of the player's current twenty score history. If so, the score is deleted from the file. Deleted T-Scores are replaced by the best
eligible tournament score (if any) in the player's handicap record that are not already in the "Best T-Score File."
d. Duration and Variation of Reduction

Handicap Index
reduction for exceptional tournament scores is calculated at each handicap revision and may vary from revision to revision based on a number of factors. These factors may include the following:
• Additional
tournament scores;
• Expiration of
eligible tournament scores;
• Variation in
10-2 calculation;
• Fluctuation of
10-2 calculation in relation to the two lowest T-Scores.
e. Handicap Committee Review of Reduction

The
Handicap Committee must review all reductions. As a result of review, the Handicap Committee may:
• Continue to allow the reduction to run its normal course, as described in Section
10-3d, or
• Further reduce the
Handicap Index. For example, the committee may conclude that the player's performance continues to be better than the potential ability indicated by the 10-3 reduction. In that case, the committee replaces the reduced Handicap Index with an even lower reduced Handicap Index, continuing to review the reduction after each revision period (See Section 8-4e), or
Override the reduction. For example, the committee may cancel the reduction to a Handicap Index for a player who has been injured and whose reduction was based on early tournament scores prior to the injury. In that case, the reduction is inconsistent with the player's scoring record. The committee replaces the reduced Handicap Index with the Handicap Index calculated under 10-2 and ceases designating it with an R. The committee will have the option to continue to override after each revision period for as long as at least two exceptional > tournament scores continue to trigger a 10-3 reduction. Once the player's scoring record contains fewer than two exceptional tournament scores, the committee must cease overriding and rely on the normal calculation under 10-2.
• Adjust the amount of the reduction. The
Handicap Committee may decide that the player's full 10-3 reduction does not reflect their potential ability, but a reduction is still necessary. In this case, the Handicap Committee may modify the amount of the reduction and the player's Handicap Index as calculated by Section 10-2. For example, if the player's 10-3 calculation is a 10.0R, but the 10-2 calculation is 15.0, the Handicap Committee could change the player's reduced value to a value of 12.5M. This does not completely override the player's reduction.
f. Reporting Requirement

Authorized golf associations
and handicap computation services must report any Handicap Index reductions under this procedure (Section 10-3b) to the golf club. If computational reports are provided to the authorized golf association, the handicap computation service must also report any Handicap Index reductions to the authorized golf association. When a Handicap Index is reduced under this section, it must be identified with the letter R (e.g., 12.3R).

TRADUÇÃO


O conceito de Handicap Index ainda não foi explicado na sua totalidade. Agora vamos completá-lo.
Toda vez que o clube informar um Gross de um jogo de torneio, deve acrescentar um T; depois do Gross. Ex:  95T, 102T. O sistema vai interpretá-los como Scores de Torneio ou T-scores.
Além do cálculo de Handicap Index descrito no item 10, computando-se os 10 melhores diferenciais ajustados e adaptados pelo Slope, um segundo cálculo é feito em paralelo somente com os scores de torneio, para se determinar se o Handicap Index do jogador deve ser reduzido ou não.
Como funciona o Index Reduzido, pelos scores de torneio ?

1. Mínimo 2 T-scores:

Para ter seu cálculo de Handicap Index Reduzido, o jogador deve ter pelo menos 2 jogos de torneio informados (mínimo 2 T-scores).

2. Diferenciais:

Os diferenciais desses jogos são calculados normalmente, conforme explicado anteriormente. Dentre os diferenciais de torneio, escolhe-se os 2 menores.
Vamos explicar com exemplos desde o início. Imagine um jogador com Handicap Index calculado 17,3 com vários cartões entregues, entre eles, 3 jogos de torneio, com os seguintes resultados Gross:  82T, 83T e 85T, todos eles jogados num campo de USGA Course Rating = 70,6 e Slope = 130.
Pelo que aprendemos seus diferenciais ficam:

82T:  (82 - 70,6) x 113 / 130 = 9,9

83T:  (83 - 70,6) x 113 / 130 = 10,8

85T:  (85 - 70,6) x 113 / 130 = 12,5
 

3. Torneio melhor que Index:
Agora, determinamos o 2º. melhor diferencial acima (10,8) e subtraímos do Handicap Index do jogador. Se o resultado for maior ou igual a 3, o jogador terá seu Handicap Index reduzido. Se o resultado for menor que 3, vale o Handicap Index calculado e não haverá redução. No nosso exemplo:

17,3 - 10,8  = 6,5

17,3 = Handicap Index

10,8 = 2º melhor diferencial do torneio

6,5 = Maior ou igual a 3. Calcular redução 

4. Cálculo da Redução do Index
a)        Calcula-se a média dos 2 melhores diferenciais de torneio:

            (9,9 + 10,8) / 2 = 10,35
            9,9 e 10,8 = 2 melhores diferenciais de torneio
            10,35 = média dos 2 melhores diferenciais
b)        Subtrai-se essa média do Handicap Index do jogador
            17,3 - 10,35 = 6,95 (arredonda-se para 1 casa decimal = 7.0)
Com esse resultado, entra-se na Tabela de Redução de Handicap.

Para se determinar quantos strokes serão abatidos do Handicap Index do jogador em questão.
Obtém-se, assim, o Redutor 5
d)        Por fim, calcula-se o Handicap Index Reduzido, acrescentando-se a letra R após o seu valor final:
Handicap Index Reduzido = Handicap Index - Redutor
Handicap Index Reduzido = 17,3 - 5 = 12,3R
Portanto, nosso jogador hipotético tem seu Handicap Index Reduzido de 17,3 para  12,3R, e é com esse Index que deve entrar nas tabelas de Course Handicap do clube onde vai jogar.

5. Comentários:

O conceito todo se baseia no fato de que se espera que, num torneio, o jogador jogue seu verdadeiro golfe e não manipule seus cartões, pois isso causaria desclassificação. Portanto, uma boa fotografia do seu verdadeiro handicap pode ser tirada daí.
Aparentemente, aqui no nosso exemplo, temos um "pistoleiro" cujo Handicap Index foi devidamente reduzido. Entretanto, essa conclusão pode ser precipitada: além de se jogar em torneios com maior concentração, o jogador pode estar jogando mal após uma doença ou cirurgia que ocorreu após os torneios analisados. Nesse caso, a redução é injusta. Este julgamento cabe ao Comitê de Handicap do clube desse jogador.
Outro aspecto fundamental do novo do sistema USGA de handicap é que todos os registros de scores de todos os jogadores devem ser públicos, para que todos vejam. Assim, todo Handicap Index com R do lado vai chamar a atenção.

6. Golfe ou Matemática?

Na prática, você, golfista amador, não deve se preocupar com esses cálculos todos. Essa é a preocupação dos clubes e federações que deverão ter sistemas de computação devidamente programados para fazer isso por você. Basta apenas saber que, com o Slope System, duas coisas importantes vão mudar no seu golfe:
a)        Seu handicap não é mais fixo e variará de campo para campo, adaptando-se à dificuldade de cada um.
b)        Seus jogos de torneio vão reduzir seu Handicap Index sempre que seus jogos avulsos produzirem resultados excepcionalmente maiores que seus torneios. Pode ser o fim dos "pistoleiros".
