Best 3 out of the last 12 were +8, +15, +17 on my home course (par 67).
Think the issue is the course rating of my home course is 72.0, which may be a default value. Anything derived from that will be suspect.
Course rating is 72.0 and slope 125. So don’t think it has been rated yet, which seems to make my WHS index meaningless at the mo. The par for my course is 67 and its SSS is lower still.
