Scoring Methods

Reference documentation for every scoring method used in Virtual CP Series.

Distance

Scores the straight-line horizontal distance (m) from window entry to window exit.

v1

Measures the straight-line horizontal distance between the point where the pilot enters the scoring window and the point where they exit. The score is in metres.

This is not the total path length — it is the displacement from entry to exit, equivalent to drawing a line on a map between those two GPS fixes. Altitude is ignored.

Default window: 8 000 – 4 000 ft MSL. Adjustable per competition.

Algorithm

  1. 1.Skip the plane ride. Same freefall detection as Max Flare.
  2. 2.Clip to window. Keep only points within the altitude band.
  3. 3.Score. Compute the horizontal distance between the first and last window points in metres.
