The proprietary indices and statistics used on Data'Scout, explained simply.
Three proprietary indices that structure the analysis on the platform.
Data'Scout proprietary global rating that ranks a player worldwide at his position, weighting performances by both his league level and his team level. A strong match in a top league counts more than a strong match in a weaker league, allowing fair comparison between a Premier League player and a Ligue 2 player.
Rating built on the same principle as the Performance Index, but without weighting by league or team level. It highlights players who overperform within their own environment, regardless of how strong their league is.
Score that measures how close two players are statistically at their position. The higher the index, the more similar the profiles are, not in raw level, but in playing style.

The model factors in the location of the shot, the origin of the assist, foot or head, type of assist, dribble just before the shot, set-piece origin, counterattack/transition context, and shot danger. Values range from 0 to 1: 0.1 xG means the shot would be scored 10% of the time, 0.8 xG means 80%. A penalty is fixed at 0.76.
Difference between goals and expected goals. Measures a player's finishing quality. A positive number means he scored more than expected and is a clinical finisher; a negative number, that he scored less than expected and struggles in the final action.
The average number of shots a player needs to score one goal.
An action (a Pass or a Touch) that happens in the opponent penalty area. Duels are excluded from this definition.
Ratio of touches in the box to total passes received. Captures attacking orientation independent of how much the player's team has the ball.
Expected assist (xA) value for a pass is the xG value of the shot that this pass led to. The pass must qualify as a 'shot assist'. Besides regular passes, crosses, corner deliveries, throw-ins and passes from free kicks followed by a shot can also carry xA value. Suffered fouls that result in penalties or direct free kicks are not included (goals scored from these events are not qualified as assisted). A pass to an offside player is just an unsuccessful pass and cannot carry xA, even if a player scores afterwards. Same logic applies to VAR-cancelled goals.
Difference between assists and expected assists. A positive number means the player delivers more assists than expected: his teammates are clinical finishers. A negative number means he delivers dangerous passes but his teammates struggle in the final action.
A pass that immediately creates a clear goal-scoring opportunity for a teammate.
The last action of a player from the goalscoring team, prior to an Assist by a teammate.
The last action of a player from the goalscoring team, prior to a Second assist by a teammate.
Combined total of goals scored and assists. Synthetic indicator of direct contribution to team goals.
Combined total of xG and xA. Measures expected offensive output based on the quality of the player's actions, regardless of finishing.
A Cross targeted to the zone within 20 metres of the opponent goal.
Crosses delivered close to the byline, typically after carrying the ball forward. Highlights players capable of combining a run and cross quality.
Offensive sequences carried by the player ending in a shot, cross, or pass into the box. Measures the ability to finalise an attacking move.
An attempt to move past an opposing player whilst trying to maintain possession of the ball.
A ground Duel for the player in possession of the ball.
A continuous ball control by one player attempting to draw the team significantly closer to the opponent goal. A run is considered progressive if the distance between the starting point and the last touch is: at least 30 metres closer to the opponent goal if starting and finishing points are in own half; at least 15 metres if they are in different halves; at least 10 metres if they are in the opponent half.
A run with the ball with a significant speed up.
Sustained periods of ball-carrying covering notable distance. Reflects the ability to drive play over time.
Total volume of offensive attempts (dribbles, crosses, progressive runs, shots…). Indicator of overall offensive involvement.
Combined total of duels won, interceptions and successful tackles. Overall view of a player's defensive contribution.
When a player attempts to dispossess an opposition player to stop an attack progressing.
When two or more players from opposing teams jump to compete for the ball.
An aggressive slide on the ground in the legs of the opposition player with a clear intention to dispossess the opponent or to clear the ball out.
Balls cut out by reading the game, without direct contact with the opponent. Measures positioning quality and ability to read passing lanes.
A Pass that is not explicitly tagged as a Long pass. Generally this means a pass of less than 40 metres long.
A ground pass longer than 45 metres or a high pass longer than 25 metres.
Share of passes received by the player compared to his teammates.
Passes that provide a strong tactical advantage: line break, opening to a free teammate. Measures vision and game intelligence.
Passes leading to an assist, the action just before the assist. Highlights creative players upstream of the final ball.
A non-cross Pass targeted to the zone within 20 metres of the opponent's goal.
A creative and penetrative pass that attempts to break the opposition's defensive lines to gain a significant advantage in attack.
A pass played into the space behind the defensive line for a teammate to contest.
A forward pass that attempts to advance a team significantly closer to the opponent's goal. A pass is considered progressive if the distance between the starting point and the next touch is: at least 30 metres closer to the opponent's goal if starting and finishing points are within a team's own half; at least 15 metres if they are in different halves; at least 10 metres if they are in the opponent's half.
Total distance covered, normalised per 90 minutes.
Distance covered between 15 km/h and 20 km/h, normalised per 90 minutes.

Distance covered above 25 km/h, normalised per 90 minutes.
Sum of high-intensity distance (20-25 km/h) and sprint distance (>25 km/h). Overview of the player's high-speed efforts, normalised per 90 minutes.
The maximum speed recorded.
The number of accelerations detected with a peak value greater than 3 m/s², normalised per 90 minutes. The action needs to last for at least 1 second.
The number of accelerations detected with a peak value greater than 3 m/s², normalised per 90 minutes. The action needs to last for at least 1 second.
Moderate slowdowns (direction changes, braking). Reflect the volume of stops and restarts, normalised per 90 minutes.
Sharp slowdowns (hard braking). Indicator of neuromuscular load, normalised per 90 minutes.
The number of High Speed Runs detected between 20 km/h and 25 km/h, normalised per 90 minutes. The action needs to last for at least 1 second.
The number of sprints exceeding 25 km/h, normalised per 90 minutes. The action needs to last for at least 1 second.
Total number of runs above 20 km/h (high intensity + sprint combined), normalised per 90 minutes.
Goals conceded by the keeper. Raw indicator, to be considered alongside the volume and quality of shots faced.
Sum of xG from shots on target faced by the keeper. Measures the objective difficulty of shots faced.
Difference between xG faced and goals conceded. A positive balance means the keeper performs above average and saves his team.
Goals prevented relative to xG faced. Allows fair comparison between keepers with different workloads.
