Vertical drop
From FIS Freestyle wiki
Vertical drop the total difference expressed in meters from the start elevation to the finish elevation.
[edit] Slope Steepness
There are two ways of measuring slope steepness. The first is a measurement using degrees, which measures the angle of the slope in degrees from the horizontal. The second is a percentage.
This is calculated using the formula 100*rise/run. Rise is the vertical change and run is the horizontal distance. A 100% slope is angled at 45 degrees.
- 10% is equivalent to 5.71º
- 20% is equivalent to 11.31º
- 30% is equivalent to 16.7º
- 40% is equivalent to 21.8º
- 50% is equivalent to 25.67º
- 75% is equivalent to 36.8º
- 100% is equivalent to 45º
A beginner slope is typically between 6% and 25%. Intermediate hills range from 25% to 40%, and expert is 40% plus.
