Shot Pattern Analysis User Guide

How to analyze your shooting performance systematically

How to Perform Analysis

  1. Upload your target image and adjust position/scale as needed. Make sure all shots are visible, that your Point of Aim is approximately in the center of the image, and that the image is level as you shot it and up is up so the app can interpret your group correctly

  2. Set your units (metric/imperial) and shooting distance, then mark a known distance on the target (10 cm or 4")

  3. Mark your Point of Aim (POA) - where you intended to hit

  4. Configure shooting parameters (caliber, position, support type)

  5. Plot your shots by clicking on each impact hole

  6. Click "Complete" to generate your analysis

Understanding Your Results

Precision

Group size: X.X MIL (Y.Y cm)

Precision measures shot-to-shot consistency - the maximum distance between any two shots in your group. Smaller numbers indicate better precision.

What it tells you: How consistent your shooting mechanics are when everything else is the same.

Accuracy

X Offset: X.XX MIL (Y.Y cm)
Y Offset: X.XX MIL (Y.Y cm)
Distance to POA: X.XX MIL (Y.Y cm)

Accuracy measures how close your group center is to your intended Point of Aim. This shows systematic errors in your shooting setup.

What it tells you: Whether your zero is correct and if you have consistent errors in your position or technique.

Worst Case Group

Group size: X.XX MIL (Y.Y cm)

The diameter of a circle centered on your POA that contains all shots. This represents your maximum potential error.

What it tells you: The largest area you need to account for when taking shots in the field. Your precision might be 1 MOA, but if your group isn't accurate (Point of Impact doesn't match Point of Aim), you need to account for more than 1 MOA. The worst case group size gives you a worst case measure to avoid wounding animals.

How to Improve Your Worst Case Group Size

Poor worst case group size indicates problems you can fix using systematic training.

A good place to start is making sure you build your shooting position properly. I use three steps and three models to help me tick all the right boxes:

  • Build your position - the ASBI model

  • Reduce or balance tension - the CAMPER model

  • Remove slack - the RGB model

These steps will help you develop natural point of aim and index correctly, so your groups get tighter. Importantly for the worst case group size, they stop your shots from wandering on the target and start aligning with your point of aim.
