Recently, a couple of people at my golf club have spoken to me about playing a round with a gross score that was equal to or lower than their age. One had just managed it, and the other would have done if one hole hadn’t been closed. Over the years several people have told me about their desire to achieve this feat; and I would certainly like to – though, being realistic, I’m probably not good enough. Anyway, these conversations got me thinking that a measure indicating how close you are to achieving it might be quite easy to calculate and maintain in the automated scoring and handicap systems that we use these days. It could simply be the gross score minus your age. To take account of courses having different par ratings, the score could be multiplied by course-par divided by 72. So, the formula would be: Gross Score x (Course Par/72) – Age. It could be called the RoundAge number (capital A to distinguish it from roundage which apparently is a local tax paid by a ship for the ground or space it occupies while in port). For example, if a 75-year-old got a gross score of 82 on a par 72 course, the RoundAge would be 82(72/72)-75 = 7. If, by some miracle, the golfer had a stellar round of 74 gross the following week, that RoundAge would be 74(72/72)-75 = -1. The RoundAge could be calculated for every card recorded, and averaged over each year to provide a longer-term graphical view of progress.
