In addition to what other have posted, if it were me, I would trade one of those 9 hole rounds for time on the practice putting green.
I'd work on reads, and speeds for the distances required. I would also work on hitting the line of my putt by hitting straight putts.
Also since GIRs are low, in addition to working on hitting closer approach shots, I would also work on chips, and pitches to give up shorter, first putts.
Approaches, pitches, and chips also require reads of the green to some extent.
I’ve been getting lessons from what I think are good instructors, using video, practicing diligently. The defect is me. Body is not going to hold up forever either. This season was not fun at all. I dunno. It’s just not fun anymore. I’ll play but I’m don’t see how that’s going to help.
I feel good if I "pure" 4 shots per round. Maybe one drive, two approach shots and one putt. I go by the Ben Hogan rule... even your bad shots should be serviceable. And those damned pure shots, that's what brings me back.
I just want to point out, for the people who have been tagging and quoting @paininthenuts, that member is banned and will not be able to respond.
I had an eagle putt today that I left 5' short. Still waiting on my first eagle.
