**Calculation using GHIN app**

If you want to use the GHIN
mobile app, it requires just a little effort.

1.
Use the “Golfer
Lookup” to find your opponent.

2.
Click on the
“star” and that puts him in your list of players.

3.
Select “Course
Handicap Calculator” .

4.
Choose course to
be played.

5.
“Select Golfers”
and “Add Golfers” to activate your opponent.

6.
Then, under your
name, “Select tees”.

It will then show the CH (Course
Handicap) for each player.

If you both have the GHIN
app, you can also just use it to calculate your own CH and share results.

**Calculation using formula**

If you know each players
Handicap Index (HI), here is how you calculate course handicap (CH):

CH = HI x slope/113 + par_rating – 72

Each tee has an associated
“par_rating” and “slope”.

e.g. Indian/Cottonwood
Copper tees are 72.2/136
(par_rating/slope).

e.g. Indian/Cottonwood Iron
tees are 69.6/127 (par_rating/slope).

e.g. Indian/Cottonwood
Silver tees are 66.0/117
(par_rating/slope).

Example: HI = 4.1

CH (Copper tees) =
4.1x136/113 + 72.2 – 72 = 5.13 = 5

CH (Iron tees) =
4.1x127/113 + 69.6 – 72 = 2.21 = 2

CH (Silver tees) = 4.1x117/113
+ 66.0 – 72 = -1.75 = -2 (you know -2
really means +2 in golf terms)

So you can see the different tees can (and do) make a
big difference.

**Who gets strokes on which holes**

Once you have the Course
Handicaps of the two players (CH1 & CH2), the player with the higher
handicap gets the number of strokes differential (i.e.
POPs = CH1-CH2)

If POPs is
even, such as 6, you get 3 strokes on the front 9 and 3 strokes on the back 9.

If POPs is
odd, such as 5, you get 3 strokes on the front 9 and 2 strokes on the back 9.

Look at the scorecard to
determine the hole difficulty under “Men’s Handicap”.

A normal 18
hole course has them labeled 1-18 in difficulty (1 being hardest).

West Woods, because it is 3
different 9 hole courses, has each course labeled 1-9.

**Calculating your maximum score on a hole for
posting score to GHIN**

When you play a normal West
Woods tournament and scoring is done with Golf Genius your maximum score on a
hole is calculated before scores are sent to GHIN.

This year (a change from
previous years) the maximum score on any hole for posting is a
Net-Double-Bogey.

Thus, you need to remember
your Course Handicap (from calculations done above) to determine which holes
you get strokes on for this purpose.

Again, puts pops on your
card as appropriate. If you are a 21 handicap, you get 1 pop and every hole,
plus an extra pop on the two hardest holes of the front 9, plus and extra pop
on the hardest hole on the back 9.

If you score a 10 on a par
5 where you get 2 pops, your maximum score (for posting) is Net-Double-Bogey.

Which for a par 5 would be
5+2+2=9 (2 for Double-Bogey and 2 for the 2 pops).
