10. DEFINITIONS AND CALCULATION RULES

This section explains the definitions and calculation formulas that Suunto G6 uses. Backswing length indicates the length of your backswing, in degrees. Consistency index is a measure of how accurately you repeat similar swings, the lower number the better. A lower consistency index means that there is less variation in the measured parameters, making your technique more solid. The Suunto G6 consistency test provides a statistically comparable result, based on a pre-defined number of swings with a specific club.

Course handicap (Course HCP) is the adjusted course handicap for the current course and tee you are playing. The Course HCP is calculated from your Handicap Index, using the following formula:

Course HCP = (HANDICAP INDEX x SLOPE RATING) / 113 + (COURSE RATING - PAR) On courses that have 9 holes, the par is multiplied by 2.

Course Rating (C.R.) represents the difficulty of a course for scratch golfers (0-hand- icap) under normal course and weather conditions. The course rating is used to adjust your course handicap for a specific set of tees.

Fairway hit (FIR) determines whether your opening shot landed on the fairway. It is registered only on holes where the par is greater than 3. (On par 3’s the opening shot should land on the green.)

The following formula is used to calculate the FIR percentage:

FAIRWAY MARKINGS / HOLES WHERE FAIRWAY IS POSSIBLE

Green in Regulation (GIR) determines your ability to play the fairway in a regulated number of shots, so that you have at least 2 putts left for playing a par.

The following formula is used to calculate the GIR percentage:
