How are novices supposed to shoot 90/70m?
They’re not! See the table above. Having novices shooting one distance shorter does mean that they will not be eligible to shoot for their club’s experienced team or for individual experienced medals. If any novice would like to shoot the experienced round in order to compete with the experienced archers applicable to them they’re welcome to do so, but their score will be considered directly equivalent to those of novices shooting the shorter round.
