| Finding the midpoint | :green_heart: Uses median, resilient to outliers | :broken_heart: Uses average, sensitive to outliers |
| Threshold | :green_heart: N/A, calculates a badness value based on the 80th percentile of track movements, works on both fast and slow moving frames | :broken_heart: 5 pixels, too sensitive on fast moving frames, too lenient on slow moving frames |
