Not sure how many strokes you should get in your weekly game? Want to test how your game holds up at the toughest courses in SoCal? What is Course Rating? December 13, By Kevin Greenup. How is the Course Rating calculated? Course Rating and Slope Rating Once all these calculations and evaluations are combined, the Course Rating team ends up with 2 numbers: the expected average score for a scratch golfer and the expected average score for a bogey golfer.
Who rates the courses? Featured Handicap. This figure is equal to the average of the better half of a scratch golfers scores. Bogey Course Rating - An evaluation of the overall difficulty of the golf course under normal course and weather conditions for the bogey golfer. The bogey rating is equal to the average of the better half of a bogey golfers scores.
Slope Rating — Golf Canada's mark that indicates the measurement of the relative difficulty of a course for players who are not scratch golfers compared to the Course Rating. The lowest Slope rating is 55 and the highest is A golf course of standard playing difficulty has a Slope Rating of The Course Rating for either golfer is determined by adding the yardage rating to the obstacle stroke value for that golfer. The effective playing length for each golfer is derived by adding the measured yardage of the course to any adjustments made for elevation, roll, forced lay-ups, wind, and altitude.
Adjustments are made to the measured yardage if there is any elevation change from tee to green elevation , if there is a prevailing wind and is it a factor wind , if the fairway landing areas are hard or soft or if the tee shots land into an up-slope or on a downslope roll , if an obstacle or combination of obstacles prevent a golfer from playing a full length shot forced lay-up , and if the course is located more than feet above sea level altitude.
The obstacle stroke value is a numerical evaluation of all obstacles topography, fairway, green target, recovery and rough, bunkers, out of bounds, water, trees, green surface, and psychology on the golf course. This evaluation process is repeated until the group reaches the green. This process is repeated on every hole and for every tee. Through this data, a scratch and bogey rating are achieved. We are then able to use these two numbers to calculate the slope number.
What if our course is not in its typical playing condition the day it is rated? Therefore, courses are rated as if normal mid-season playing conditions existed i.
For the majority of the golf courses in the Met Area, mid-season conditions with respect to fairways, length of rough, foliage, and speed of greens, exist between spring and fall. Because the USGA requires all courses to be rated at least once every 10 years, it is important for the team of course raters to obtain accurate, mid-season course conditions. How often is a course rated? The USGA requires all authorized golf associations to periodically review the ratings of their courses and to revise them if necessary.
The MGA is required to re-rate a golf course within a year period. All newly constructed golf courses often change due to their maturity. Therefore, the MGA rates these courses times within the first 10 years to account for these changes. However, more than likely you are not in need of a full course rating. Many times the MGA can send out a representative to view the changes made on the course. These changes can then be entered into the USGA Course Rating software to calculate an updated course rating and slope rating.
To fully understand how course rating and slope numbers ultimately affect your Handicap Index, you must first understand how a Handicap Index is derived. Using equitable stroke control the maximum score you can take on a hole for posting purposes , a player takes his adjusted gross score and subtracts the course rating.
Multiply that number by slope rating of a course of standard difficulty , and divide by the slope rating of the tees played. Round to the nearest 10th. These 10 differentials would be totaled and divided by the number of differentials used 10 , multiplied by. Often, players focus too much on what the slope number is when it is the course rating number that drives the system. For example:. Course A Course B This is not necessarily true.
Why is our course rated so high? Golf courses are rated based on the measured length of the course from each set of tees. The measured length of a particular set of tees is taken from the permanent marker to the center of the green. Accurate permanent marker placement is essential to an accurate course rating. Permanent markers are to reflect the average placement of the movable tee markers.
Permanent markers should be placed on the teeing ground at a spot where the movable tee markers can be placed on either side to consistently reflect the overall length of the hole and course. For instance, if a course consistently placed their movable tee markers in front of the permanent markers on average 10 yards per hole, the golf course would play almost one shot easier than the rating indicates.
This practice would result in an artificially low Handicap Index. The USGA recommends placing the permanent markers in the middle of every teeing ground. When two tees share one teeing ground, the teeing ground should be divided in thirds. This process maximizes the ability of the golf course to use the entire teeing area and gives the best chance of reflecting the overall yardage. At no time should a permanent marker be less than two yards from the front of a teeing area or less than four yards from the back of a teeing area.
Courses are encouraged to consult the MGA for assistance in determining accurate placement. Who allocates handicap stroke holes? The MGA does not assign handicap strokes to individual holes as a result of the course rating.
