Average Slope Rating
I read that the average course Slope Rating is 113. I've never seen a Slope lower than 120. What gives?
A: A When I introduced the system in 1982, the theoretical average Slope Rating was 113 because USGA data showed that scores go up on average 1.13 strokes per handicap stroke. The actual average Slope Rating is 120. The majority of courses in coastal states have Slopes of 121 and higher. Many Slopes lower than 118 are mid-American public courses. The lowest is 55 (short par-3 course), and the highest is 155.
