# General Club Noticeboard : 2018 Annual Handicap Reviews

The 2018 Mens and Ladies annual handicap reviews have both been completed and posted in the respective locker rooms for your own information and everyone else's annoyance / amusement (depending on who it is!). Please check to see if your handicap has changed before you next play.

The revisions were calculated in line with CONGU guidelines as follows:-

1. The player’s “Median Gross Differential” (MGD) is calculated by listing the nett differentials (number of shots over Competition Scratch Score) for each Qualifying round in ascending order and finding the score in the mid-point of the list.
2. The player’s “Median Nett Differential” (MND) is calculated by subtracting theiryear-end handicap (H) from the MGD.
3. The player’s “Ideal (Target) MND” is calculated by applying the formula:
MND = (0.237 x H) + 1.5745.

The target MND is compared with the actual MND. If the difference is less than 3, no handicap change is required. If the difference is between 3 and 5, a 1 shot adjustment is required. If the difference is greater than 5, a 2 shot adjustment is required.

EXAMPLE 1

Player with a year-end handicap of 7.5 having returned scores of 6, 7, 10, 10, 16, 17 & 21 over CSS.

MGD = 10

MND = 10 – 7.5 = 2.5

Target MND = (0.237 x 7.5) + 1.5745 = 3.35

MND  – target MND = 2.5 – 3.35 = -0.85

So the player is within the tolerance of +/-3 and can be considered correctly handicapped.

EXAMPLE 2

Player with a year-end handicap of 14.1 having returned scores of 15, 16, 18, 18, 23, 24, 25, NR & NR

MGD = 23

MND = 23 – 14.1 = 8.9

Target MND = (0.237 x 14.1) + 1.5745 = 4.92

MND  – target MND = 8.9 – 4.92 = 3.98

So the player is within the range of +3 to +5 and is recommended for a handicap increase of 1.

EXAMPLE 3

Player with a year-end handicap of 22.0 having returned scores of 18, 20, 20, 23, 24, 25, 26, 32 & NR

MGD = 24

MND = 24 – 22.0 = 2.0

Target MND = (0.237 x 22.0) + 1.5745 = 6.79

MND  – target MND = 2.0 – 6.79 = -4.79

So the player is within the range of -3 to -5 and is recommended for a handicap decrease of 1.

Hopefully this helps your understanding of the Annual Review process!
