After about 2 years, and now realizing a dramatic improvement in my putting game (I'm hitting 90% within 10 m, 50% within 15 m), I'm almost down to par regularly on some of the more challenging courses around NorCal. Yet I almost always make mistakes that lead to several bogies, and so I always need several birdies to balance them out.
My drives have been improving slowly but surely with time. There is no hole I've seen that I can't par, although longer holes require a very good upshot to lay up safe because my distance is still not much better than 320' max (including the skip). But putting has been everything in improving my scores.
Basic message: Practice putting. A lot. That is your fastest route to par.
I've been working my forehand game again, and forcing myself to drive forehand on every hole makes for good practice and learning to better shape lines. But it hurts my tally. Yesterday I had 5 bogies but only 2 birdies at my 18-hole home course (Shady Oaks, Orangevale, CA, SSA~51, par=54), but if I had been able to drive several of those holes backhand I would have had only 1 or 2 bogies (I badly shanked several forehand drives, but saved by very good backhand upshots usually with my trusty Classic Roc). Winners of the St Patrick's classic tournaments at this course are typically shooting -7 or so under par...I've got a lot of work to do to get to that point!
