Totally agree as well it dont, in fact has an adverse effect on the better shots.
Generally speaking we used to use an handicap system back in 93/94 season. Above statistics look very very familiar.
A graders clearing the courses ending up 2nd and 3rd behind winner a legit B grader finishing with 2 more than the max possible. Meaningless.
I do this sport for enjoyment, take it as it comes on level pegging in the top grade regardless of actual grade and accept i aint good enough.
