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
Versioning policy
Minor refinements become new versions; fundamentally different measurements become new scorer methods.
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.
Scoring window
Default window: 8 000 – 4 000 ft MSL. Adjustable per competition.
Algorithm
- 1.Skip the plane ride. Same freefall detection as Max Flare.
- 2.Clip to window. Keep only points within the altitude band.
- 3.Score. Compute the horizontal distance between the first and last window points in metres.
Parameters
| Parameter | Default | Description |
|---|---|---|
| window_hi_ft | 8 000 | Top of the scoring window in feet MSL. |
| window_lo_ft | 4 000 | Bottom of the scoring window in feet MSL. |
| freefall_threshold_ms | 25 m/s | velD threshold used to locate freefall start and skip the plane ride. |
Score breakdown
| Field | Description |
|---|---|
| window_hi_m / window_lo_m | Scoring window bounds in metres. |
| freefall_start_t | Time (s from track start) where freefall was detected. |
| points_in_window | GPS samples within the scoring window. |
| entry_lat / entry_lon | Coordinates of the window entry point. |
| exit_lat / exit_lon | Coordinates of the window exit point. |
| distance_m | Horizontal distance between entry and exit (m). |
