SInce I've been on the back tees though, I've always kind of wished the average wouldn't ever saturate just to have a truer average.
Everyone has a "lifetime" Average kinda built into their stats. It is not 'since being on the back tees' -- but it is at least the same for everyone (with a few exceptions for strange stats anomalies).
A standard 72 stroke course is normally 4 x Par 3s, 10 x Par 4s and 4 x Par 5s.
So simply take your average score on P3s, P4s and P5s and stick them into that equation.
Say your average strokes are currently:-
Par 3s 2.91
Par 4s 3.81
Par 5s 4.40
So - against a 72 stroke course your average would be 4x2.91 + 10x3.81 + 4x4.40
= A Lifetime Average of 70.88
It's probably more meaningful than the Saturated Average!
