We use a formula similar to others. The following steps are
taken to calculate it.
First, we calculate the handicap differential for each round
using the SSE (scratch scoring estimate) Rating (what a scratch golfer would score) for the courses
HCP Dif=Score - SSE
Example: Your score is 55, the SSE
The formula would be (55 - 50).
This differential is calculated and recorded for each
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
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 0.90. 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/#
