pdb1: I think I will wait until someone comes up with something better . Don't worry . I won't hold my breath .
Look no further pdb1! Here's your statement with supporting evidence for those in your CC who may not believe everything they read on the internet.Your Average Score is based on multiple scores for ranked rounds completed ONLY within your current Tier. The full 18 hole ranked round score is used to get the number that contributes to your average. 9 hole ranked round scores are doubled to get the number that contributes to your average. Scores from the Par 3 stroke play courses and Par 5 courses are not counted towards your average.
Once you are promoted to a new tier your average is reset. All ranked round scores within that tier are counted towards your Average Score until the number of ranked rounds reaches a Saturation Point Number. (The number of rounds to reach the Saturation Point varies by Tier.) Once you reach the Saturation Point only your best N scores will count towards your Average Score, where N is the Saturation Point Number of rounds.
If your Tier Saturation Point Number is 40 for example and you have 50 ranked rounds posted in that Tier, only the best 40 scores of the 50 count towards your Average Score. If your highest score of the 40 best rounds is 73 and you post a new score of 74, the 74 does not count towards the Average Score. Your Average Score does not change. If on the other hand you post a new score of 72, the 72 is better than the worst 73 so the 73 is replaced by the 72 and you Average Score will go down. Once you reach the Saturation Point Number of rounds in a Tier your Average Score will only go down.
I looked at the scores of some recent new players. These 2 images show a full 18 ranked round score counts fully towards the Average Score:
These next two images show a 9 hole ranked round score is doubled:
Here's how a mix of 18 and 9 are calculated:
This image shows Par 5 courses do not count towards Average Score:
And last but not least, these images shows a Par 3 course being excluded from Average Score:
