Two matches can share the same score and still be moving in opposite directions. A 1-1 game may be settling into a controlled finish, or it may be opening up as both teams create chances. The score alone cannot show that difference.
What the index measures
The Live Performance Index is a descriptive match-state score. It combines the attacking pressure a team is producing with the resistance it is showing without the ball. The trajectory is recalculated as the live evidence changes.
- Attack pressure from the current match flow and recent pressure windows.
- Defensive resistance from the opponent pressure a team is absorbing or limiting.
- Direction of travel across the latest live states, rather than one isolated snapshot.
- Score and minute context, so the same pressure means different things at 20 minutes and 82 minutes.
What it is not
The index is not a win probability and it is not an odds edge. Win probabilities remain a separate market read. The index explains performance shape: who is pushing, who is resisting, and whether the balance is changing.
How it supports the match read
A useful WHY should do more than repeat the score. Edge93 can point to a pressure shift, stronger chance creation, or declining attacking output because those are the same inputs feeding the trajectory. The reason and the visual therefore describe the same state.
Use the trajectory to understand match direction, then read it beside the live probability, current bookmaker odds, score, minute, and supporting evidence.
