Scoring Methods
Reference documentation for every scoring method used in Virtual CP Series.
Time
Scores the time (s) spent inside the scoring window.
v1
Versioning policy
Minor refinements become new versions; fundamentally different measurements become new scorer methods.
Measures the elapsed time between the first GPS sample inside the scoring window (entry) and the last GPS sample inside the window (exit). The score is in seconds.
A pilot who slows down and spends more time descending through the window will score higher. A pilot who enters high and exits low quickly will score lower.
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. Subtract the timestamp of the first window point from the timestamp of the last window point.
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_t | Timestamp of the window entry point (s from track start). |
| exit_t | Timestamp of the window exit point (s from track start). |
| time_s | Elapsed time in the window (s). |
