Rotation breakdown
Use By rotation to compare Sideout %, Break %, evaluation mix, efficiency, and impact across rotations. Tap a rotation row for player-level detail.
Treat small samples carefully. A strong percentage from only a few rallies is a lead to investigate, not a final conclusion.
Player × rotation
Choose a player to see their efficiency in each on-court position. The larger number is the selected player's value; the value in parentheses is the team baseline for everyone who played that position.
The baseline does not change when you switch players. It is a reference point, not that player's personal average.
Rally analysis
Rally analysis groups attacks by the quality of the pass entering the attack, such as after a perfect pass or after a positive pass. This helps separate transition problems from first-ball offense.
Reception attack comparison
In the By player view, the Reception tab adds a Compare by switch at the right of the visible-players row.
- Reception (default): the reception itself — the pass-quality mix and its efficiency.
- Reception attack: the attack immediately after that player's reception. Both the scatter plot and the table switch over.
In reception-attack mode the scatter plot becomes X = reception efficiency/attempt and Y = reception-attack efficiency/attempt. Both axes use the same scale, so a gray dashed Y = X diagonal is drawn as a reference. The target is the upper right: good passes the team converts into points.
A player below the diagonal is not getting much offense out of passes that grade well. There are two ways to improve, and they combine into a higher sideout percentage:
- Move right — pass better. Turn more serves into perfect or positive passes and raise reception efficiency itself.
- Move up — raise the quality of the pass. Even at the same grade, aim for a height and speed the setter can take without moving, and a timing the hitters can approach from.
A player above the diagonal converts better than the pass grade alone suggests; share what is working after the pass with the rest of the team. Tap the i button on the plot for the same explanation with a diagram.
The table switches to attack results, with a leading Rec. column for how many receptions that player took. Tap a row to see who actually hit those attacks.
Reception attacks are counted the same way as on the Reception attack tab: only the first attack right after the reception, excluding free-ball returns. It counts on the receiver's row even when someone else hit it. Opponent receptions are not recorded, so this comparison has no opponent row.
Opponent comparison
Compare your team with the opponent across core metrics. For reliable player-level opponent data, link an Opponent analysis match.
Without a linked analysis match, opponent values are limited to what can be inferred from your own entries.
Shot placement
Link an Attack analysis match to visualize attack origin, set location, target, and outcome on court diagrams.
Below the player selector, a Receiver selector narrows the view to the attacks that came right after one player's reception — useful for asking whether the offense goes to different places depending on who passed. Choosing a receiver switches the view to reception attacks only, and clearing it puts both back.
The receiver is only known when a standard match has an analysis match linked to it: the analysis mode records where the reception happened but not who took it, so the app matches each rally to the standard match by set and score to recover the passer. The selector does not appear without that link or when you open the analysis match directly. Linked matches work the same way in the aggregate stats page.
The filter rows from the line mode down to the reception-attack and rotation row fold into a single bar, so the court diagram stays near the top. Tap the bar to open or close it; while closed it summarizes the conditions in effect, for example Attack → target / #6 / Rec. #6 / Front row only. The evaluation filter, shot-type filter, set-location zones, and the totals bar are always visible.
Growth charts
The team Stats page can compare a metric across multiple matches and a selected date range. Use consistent input standards across matches; a change in how actions are graded can look like a performance change.
Customize evaluation weights
Editors and administrators can change the integer weight assigned to each evaluation. Use Reset to defaults to restore the standard ATaMa volley values.
Document custom weights
Changing weights changes the meaning of efficiency and impact. Agree on the scale as a team and avoid changing it during a comparison period.
Export CSV
Use Export CSV to download the current player, rotation, or rally-analysis view. Test matches may disable export. The exported labels follow the selected app language where supported.

Supported views can be saved or shared as a PDF or ZIP report. Check the match name, set filter, and selected action before generating the file.
