Scoring Methods
Reference documentation for every scoring method used in Virtual CP Series.
Max Vertical Speed
Scores the highest downward speed (m/s) recorded within the scoring window.
v1
Versioning policy
Minor refinements become new versions; fundamentally different measurements become new scorer methods.
Finds the single GPS sample with the highest downward speed (velD) within the scoring window. The score is that speed in m/s. The altitude at which the peak occurred is recorded in the breakdown. The display also converts the score to mph and km/h.
Note: velD follows the FlySight convention where positive values indicate downward motion. Higher numbers mean faster descent.
Scoring window
Default window: 8 000 – 4 000 ft MSL. Adjustable per competition.
Algorithm
- 1.Skip the plane ride. Scan for 3 consecutive samples with
velD> 25 m/s; fall back to the highest-altitude point for canopy-only files. - 2.Clip to window. Keep only points within the altitude band.
- 3.Score. Return the maximum
velDvalue found in the window.
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. |
| max_vspeed_ms | Peak velD recorded in the window (m/s). |
| alt_at_max_speed_m | Altitude at which the peak velD was recorded (m). |
