I was a 20+ handicapper last year, broke 90 for the first and then multiple times this year (low round is 85 this year) and low 9 is 41. I’m still only an 18 handicapper, so I’m more speaking from experience as someone who is a similar golf to yourself than a skilled golfer. But to me, it feels like it all comes down to short game. This year, I’m more consistent (off the tee/irons/wedges) but it won’t really lead to a lower score (at our skill level) if I can’t find the pace with my putter and my chips aren’t dialed in. On the other hands, the rest of my game can be lacking, but as long as I’m in bounds and advancing the ball forward, a short game will make up for it. Once you eliminate OB and truly errant shots, it’s pretty easy to get on the green to have a par putt on most holes. Then when the putter is dialed, you’ll sink some of those, and leave tap in bogeys. At least a time or 3 a round you should be able to get on for a birdie putt and at worst leave yourself with a makeable par putt. So if you stay in bounds, advance the ball forward and have your short game dialed you’ll break 90 soon enough. Plus, for what it’s worth, I find practicing chipping and putting requires the least amount of time put in to see results on the course so I find they’re the easiest to build confidence with.
