How do you get a rating for your course?
Hosting a PDGA event is the official way to get an SSA rating for your course. Your course gets an SSA rating when at least 5 current PDGA members with official ratings over 799 play it in PDGA competition. The rough SSA calculation for an 18-hole course with average foliage density is to take the total course length in feet, divide it by 285, then add 30. This will get within a few shots of the SSA and even closer if you adjust upward or downward for more or less than average foliage on the course.
