Since Summer 2009 the jury can change the length of the inrun during a qualification- or competition round without making a restard necessary. This shall give the jury more possibilities to react to changing conditions.
In order to compensate for the changed inrun-length a jumpers gets points deducted or added, depending on whether the gate was moved up or down. These points are calculated based on a certain formula that is adjusted to every hill individualy.
One additional meter of inrun on a large hill translates into about 5 m more flight. The difference between the gates is between 60 cm to 70 cm on most jumps. If one meter inrun means 5 m more distance, that means that changing the inrun by 60 cm results in a difference in jumped distance of 60 % of the f value.
If the bar for jumper B is moved 50 cm lower compared to jumper A due to headwind, a further 4.5 points will be added to his total. (50 % of 1 m inrun/5m jumping distance is 2.5 x 1.8 points (meter value) = 4.5 points).
If the bar for jumper C is moved 50 cm higher compared to jumper A due to tailwind, 4.5 points would be deducted from his total.
