Other leagues may set different standards for their level of play. Size is only a guideline especially if your looking to build your own court. This will give you a better sense of depth especially if you bring your new found skill to a tournament away from your home grown court. My teammate and I have used an easy way to record every single throw made during a match. It's not unlike keeping score in a baseball game.
Every throw has a characteristic and a limited result.
We are currently researching a way to market this to all bocce leagues in a way that everyone can understand and benefit. I am looking at both a hard copy score book and a software program. Please feel free to send me any comments. I hope these questions and answers help. Hopefully it will cut down on some the e-mail questions I keep receiving.
