such that the distance can be derived by multiplying the corresponding staff section by 100. (This diagram is a schematic representation). Accuracy of the distance measurement: 10 – 30 cm Example: Reading on upper stadia line B = 1.829 Reading on lower stadia line A = 1.603 Staff section I = B-A = 0.226 Distance = 100 I = 22.6 m B A D 11
