To qualify this, I never kept a handicap until 1998-9 and I recall that it was a 5.7 at its best and hovered in the mid 6 range. Previously to 1998, I did not keep a handicap, but I don't see it being lower than it is today because I am more consistent now, especially given the modern equipment. I just found a letter from the USGA reinstating my amateur status back in 1996. Before that, I was a PGA Apprentice when I was getting my Master's degree (I previously worked for a golf sportswear company and was laid off during the Gulf War recession). When I finished school, I dropped the golf aspirations mainly due to the the tumultuous times in the golf industry in this area and it was not something that I saw a real future in. Many of my friends were getting laid off including my brother who was an assistant pro at an exclusive club in Broward (I think the head pro really pissed off someone and they cleaned house). I stayed around golf and ran a summer golf camp for a few years and then took my hiatus as career and family demands required more attention.
When I returned to golf a couple of years ago, I knew that my main resource, time, was limited. I decided that if I was going to play, that I would want to play well enough to enjoy myself on any given weekend. To my surprise, with a little practice I returned to a mid 8 index. Soon, with a couple of lessons, I was playing to a 7 and when I broke into the 6s, I started this blog to document my journey with my goal of being a solid 5. I don't know if it had helped anyone to read it, but it has helped me. I don't know how much better I can get, but I am pretty happy with my results so far. So to answer the question, yes this is my lowest index of record and the most consistent golf that I have played.
