The series statistics provide key data about your shot grouping, tracking consistency, accuracy, and precision. These values are displayed at the top of the target view and include:

✅ Mean Point of Impact (MPI)
✅ Center-to-Center Distance (C-C) / Extreme Spread
✅ Minimum Bounding Circle (MBC) / Minimal Enclosing Circle (MEC)
✅ Minimum Bounding Rectangle (MBR)

Each of these statistics gives important insight into your shooting performance. Below is an overview of what they measure, how they are displayed, and other commonly used terms that may describe the same concept.

1. Mean Point of Impact (MPI)

Shows the average hit location of all shots in the series.

• Displayed as X and Y coordinates (mm).
• Also indicated as an orange rectangular crosshair in the target view.
• Indicates whether shots are grouping in a specific area relative to the target center.

Other terms used: Some shooting disciplines refer to MPI as Center of Impact (COI) or Group Center. Regardless of terminology, the purpose remains the same—to define the central tendency of the shot group.

2. Center-to-Center Distance (C-C) / Extreme Spread

Measures the longest distance between any two shots in the series.

• Shown in millimeters.
• Represents the maximum shot spread in the group.
• Commonly used in precision shooting to compare consistency across different shot groups.

Other terms used: This statistic is often referred to as Extreme Spread (ES) or simply Max Spread. 

3. Minimum Bounding Circle (MBC) / Minimal Enclosing Circle (MEC)

Smallest possible circle enclosing all shots in the series.

• Represents the overall group size.
• A smaller MBC indicates a tighter group, while a larger MBC suggests greater dispersion.
• Used to evaluate precision and consistency.

Other terms used: Some disciplines call this the Minimal Enclosing Circle (MEC). 

4. Minimum Bounding Rectangle (MBR)

Smallest rectangle that encloses all shots in the series.

• Displays width and height (mm) of the shot group.
• Helps determine if shots are spreading more horizontally or vertically.

Other terms used: This concept is sometimes referred to as a Bounding Box or Dispersion Rectangle, particularly in statistical analysis and military shooting contexts. It is a valuable tool for evaluating consistency over multiple series and identifying directional bias in shot placement.

Configure series statistics

The display of series statistics is user-configurable. You can choose to show all, some, or none of the available statistics based on your preference.

To select which statistics to display:

1. Tap the settings button on the right side of the screen.
2. Navigate to the “Statistics” menu.
3. Select or deselect the statistics you want to be displayed.

Click settings button located in the lower right of the screen. Then statistics.

Select which you want to see

Additionally, the statistics can be shown in metric (millimeters) or imperial (inches and fractions). This can also be adjusted in the settings → systems → regional.
