The scores thrown by propagators each round are used to calculate the SSA rating for a specific course layout. A propagator is a current member whose rating is over 799 and is based on at least 8 rounds. As long as there are 5 propagators playing a course layout, ratings can be calculated. The average rating of all propagators will equal the average rating they get for the round Ė always. If the same course layout is used more than one round, the scores from multiple rounds will be used to determine an overall SSA, as long as the individual round SSAs come out close to each other, so everyone gets the same rating for the same score on the same course. If the SSAs are significantly different, likely due to varying wind conditions, the round ratings will be calculated separately. If a propagator shoots more than 60 points below their rating, their score will not be used in the SSA calculations.
Why is the SSA calculated for each round rather than using a fixed course rating like ball golf?
Thereís no way to determine what an official SSA value would be for a course simply by taking measurements, looking at foliage, fairway widths and accounting for hazards. Not only that, itís common for TDs to add temp holes, change tee or pin positions, or use new courses such that no SSA would be on file for that layout anyway. Using the scores of players with established ratings to produce an SSA has proven to be an accurate way to indicate how the course played that round. The only weakness of this system is that we require only 5 propagators to generate an SSA. Statisticians would prefer we use at least 30 propagators minimum for better accuracy. However, the PDGA has chosen 5 so that more players would get ratings. Some smaller divisions who play shorter layouts may not have very many propagators on a layout that round and would not get ratings in several events. The slightly higher inaccuracies produced with this system for individual rounds tend to even out over time. Plus, no round rating remains in an active playerís rating more than 12 months before it disappears.
