**Answers:**
**1. Can my MobileGolfStat (MGS) handicap be
used as an official USGA handicap?**
While your MGS handicap is calculated with the same formula
as the USGA, it can not be used as an official USGA handicap. It
is for recreational purposes only.
**2. How is my MobileGolfStat Handicap
calculated?**
We use the same formula as the USGA. The following steps are
taken to calculate it.
**Step 1**
First, we calculate the handicap differential for each round
using the USGA Course Ration and Slope Rating for the courses
played.
**HCP Dif=(Score - Course Rating) x 113 / Slope Rating **
Example: Your score is 85, the course rating
is 72.2, and the slope is 131.
The formula would be (85 - 72.2) x 113 / 131.
This differential is calculated and recorded for each
round.
**Step 2**
The next step is to figure out how many differentials to use.
Only the lowest differentials are used. If you've only entered
11 rounds then only the 4 lowest differentials are used. See
the following chart:
**Number of Differentials Used**
Rounds Entered |
Differentials Used |
5-6 |
1 lowest |
7-8 |
2 lowest |
9-10 |
3 lowest |
11-12 |
4 lowest |
13-14 |
5 lowest |
15-16 |
6 lowest |
17 |
7 lowest |
18 |
8 lowest |
19 |
9 lowest |
20 |
10 lowest |
**Step 3**
Next, we find the average of the differentials used. If we're
only using the 4 lowest then we add them together and divide
by 4. We then multiply this by 0.96. All the digits after the
tenths are dropped (not rounded) in the result. This gives us
your handicap index.
**HCP (handicap) index = (sum of differentials/#
differentials)*0.96**
**Step 4**
The HCP index is used to find the course handicap. This is
because course difficulty varies and your handicap on one
course may not be equal to your handicap on another.
**Finding
the Course Handicap**
The course handicap is calculated using your HCP index and
the Slope Rating of the Tees Played divided by the average slope
rating of 113.
**Course Handicap=(Your HCP Index) x (Slope Rating of
Tees Played)/113**
Example: You have a HCP index of 16.7 and you played a
course with a tee box slope of 127.
Course HCP = 16.7 * 127/113 = 19 (Course Handicap is rounded
up or down)
In this example the course you played is harder than the
average course which is why your course handicap (19) is higher
than your handicap index (16.7).
The Course Handicap is the number you use to determine how
many strokes you get.
Equitable Stroke Control (ESC) is the system put in place by
the USGA to eliminate the effect of "distaster holes." You know,
that one hole per round where you put three balls in the water
and then 5-putt. It's also a way to combat those pernicious
sandbaggers who intentionally blow up on a hole in order to
raise their handicaps. Equitable Stroke Control puts a limit on
the number of strokes you can write down on the scorecard for
any one hole, based on your course handicap. For example, on
that one disaster hole you might have taken 14 strokes (get to
the practice range, buddy!) to get the ball in the cup. But
based on your course handicap, ESC might require you to post
only a "7" on the scorecard you turn in.
Taking the "14" might throw your handicap index out of whack.
And remember, the handicap index is not meant to reflect your
average score, it's meant to reflect your best potential.
**3. What is Equitable Stroke Control?**
The USGA came up with Equitable Stroke Control (ESC) as a
system to eliminate the effect disaster holes have on your
handicap. The one or two holes per a round where you really blow
up. ESC puts a limit on the number of strokes you can take on
any one hole based on your course handicap. For example is you
have a 12 on a hole and your course handicap is 16 then the
worse you can write down is a 7. See the chart below to find out
the maximum score you can take based on your course handicap.
MobileGolfStats does not automatically
figure the Equitable Stroke Control. This is left up to you when
inserting your scores.

**4. What do all the acronyms stand for on
the different tables and charts?**
DIF = Drives in Fairway
GIR = Greens in Regulation
Scramble = This is the ability to still make par when not on the green in regulation. For instance you play 18 and have 8 GIRs. Then for the 10 greens you missed you made par on 4 of them. This gives you a Scramble % of 40%. The higher the scramble % the better.
Putts/Hole = Average putts per a hole
Putts/GIR = Average putts when getting on the green in
regulation
Putts/Round = Average putts per a round of golf (18 holes
only)
1st. Putt Dist. = Average distance of your first putt
Up/Down = Percentage getting up and down in 2 strokes
from off the green
Sand Save = Percentage of getting out and in the hole in 2
strokes
Drive Lft = Percentage of drives left
Drive Rt = Percentage of drives right
Hole Avg. = Average score on a hole where par=0
Post Birdie Avg. = Same as Hole Avg. except on holes after a
birdie are counted
HCP Ind. = Your handicap index
HCP Dif. = Your handicap differential, used to calculate HCP
Ind.
Scoring Average = (your score)/(course par)*72 This is a great way to compare your scores no matter if you play 9 or 18.
5. **Will you be adding new features?**
Yes, we continue to add new features whenever we have time.
Not only do we run the website, but we use it to track our own
stats. So were always looking for cool stuff to add. If you've
got a suggestion send us an email using the form on the
"Contact" page.
**6. Can I enter a 9 hole round or less?**
You can enter a 9 hole round, but you must make sure that you
specify it as a nine hole round during the record round
process. You will see a selection for 18, front 9, or back 9.
Partial rounds, less than 9 holes for example, are counted as
full rounds. These should be avoided since it will throw off
your stats. **7. What happens if
someone deletes a tee box that I've used for one of my rounds?**
Don't worry...once you record a round all of the tee box
information is saved with your round. So even if someone deletes
the tee box it won't effect your stats! This is why it's
important that the tee box information is correct before you
submit your round. |
