You start on the 50 point rung, one score per week. Working your way up to the 250pt rung. Example: First night you shot a score of 161 points, you would be placed on the 50pt rung. Second night, you shoot a score of 154 points, you would be placed on the 100pt rung. And work your way up to the 250 point rung. The reason for this is consistency, we want consistency to maintain or improve our scores. Once you reach the 250pt rung, you should be fairly consistent, now its fine tuning to get closer to that 300 point mark (perfect score). Good luck, and most of all Have Fun!
