From the following set of observations we get the following results: Div of Stride Level 38.50 35.25 36.25 38.00 38.00 39.50 Total 225.5 div of stride level Div of Alidade Level 28.75 27.00 27.25 25.25 28.75 27.75 164.75 div of Alidade 1 div of the stride level = 164.75/225.5 div of alidade level. But 1 div of the Alidade level = 8.31 1 div of the stride level = 164.75/225.5 x 8.31= 6.07
