Stats — basics
Open the Stats page
Open a match card and choose Stats, or tap View detailed stats from the results screen. Use the set filter to show the whole match or one set.
Efficiency and impact
Efficiency per attempt
Efficiency per attempt is a weighted average of recorded evaluations. A positive result adds value, a negative result subtracts value, and the total is divided by the number of attempts.
It answers: How good was the average attempt?
Impact per set
Impact per set combines efficiency with volume. A player who maintains quality while taking more useful actions will generally have a larger value.
It answers: How much did the player contribute per set?
Team-specific weights
ATaMa volley's weighted metric is based on graded volleyball actions, but it is not the single traditional attack-efficiency formula. Administrators and editors can adjust evaluation weights to match the team's priorities.
Player view
Choose an action tab such as Serve, Reception, or Attack. Each row shows a player, evaluation counts, attempts, efficiency per attempt, and impact per set.
- Compare efficiency only when players have enough attempts.
- Use impact to see the combination of quality and workload.
- Tap the information button for the exact metric explanation.
Rotation view
Rotation view compares all six serve-order rotations. Important rates include:
- Sideout %: points won while receiving serve
- Break %: points won while serving
Use the team total as a baseline, then open a rotation row to see which players and actions drove the difference.
Team and opponent rows
The team row aggregates your recorded actions. Opponent values may be derived from the outcomes recorded from your team's point of view unless a dedicated opponent-analysis match is linked.
