The higher the slope, the more difficult the course is. When the slope rating system was first put into effect, the USGA set the slope for an "average" golf course at 113; however, not many 18-hole golf courses have slope ratings that low. Some do, but the real-world average is higher than 113.
That would be like your...height, skin color and eye color ect...
