Invasion and Acceleration Indices
- Invasion Index: Measures a team's effectiveness in reaching scoring positions; calculated by evaluating scoring probability from event locations within possession phases.
- Acceleration Index: Evaluates how quickly a team reaches dangerous zones relative to its possession duration, calculated using the ratio of the invasion index to the time squared of the possession phase.
- Example: In the Roma vs. Fiorentina match on April 7, 2018, Fiorentina had higher averages in both invasion (0.27) and acceleration (0.07) indices compared to Roma (0.23 and 0.06, respectively).
