What is the concept of elevation in terms of sea level?

Back

Elevation refers to the height of a point above or below sea level. Positive values indicate heights above sea level, while negative values indicate depths below sea level.

How do you calculate the difference between two elevations?

Back

To calculate the difference between two elevations, you subtract the lower elevation from the higher elevation. If one is above sea level and the other is below, you add their absolute values.

How do you calculate total loss in a series of negative movements?

Back

To calculate total loss, sum all negative movements. For example, a loss of 12 yards and a penalty of 5 yards results in a total loss of 12 + 5 = 17 yards.
