Question 1

How does Shotalyze detect bullet holes?

Accepted Answer

Shotalyze uses a YOLO-based computer vision model fine-tuned on thousands of shooting target images. Upload a photo of your paper target and the app automatically detects each bullet hole, measures group size, and classifies your shot pattern. If a hole is missed, the manual correction editor lets you add, move, or remove detections.

Question 2

What is MOA and how is group size measured?

Accepted Answer

Group size is the distance between the two farthest bullet holes (extreme spread), measured center-to-center. MOA (Minute of Angle) converts this to an angular measurement: 1 MOA equals approximately 1 inch at 100 yards or 29mm at 100 meters. MOA lets you compare groups shot at different distances.

Question 3

What causes low-left shots for right-handed shooters?

Accepted Answer

Low-left is the most common pistol shooting error for right-handed shooters. It is typically caused by trigger finger mechanics pulling the muzzle sideways, anticipation or flinch pushing the muzzle down before the shot breaks, or grip imbalance letting the gun torque. Drills like the wall drill, ball-and-dummy, and penny drill target these root causes.

Question 4

Does Shotalyze work with ISSF and NRA targets?

Accepted Answer

Yes. Shotalyze includes a built-in target library with correct ring dimensions for ISSF targets (10m air pistol, 25m rapid fire, 50m free pistol) and NRA targets (B-8, B-16, B-27). You can also create custom targets with your own specifications.

Question 5

Is Shotalyze free to use?

Accepted Answer

Shotalyze has a free tier that includes daily analyses, group stats, pattern detection, and one coaching cause per analysis. Paid plans (Hobby and Pro) add more analyses per month, all coaching causes, trends, heat maps, ammo management, per-gun analytics, scope zeroing, and CSV/PDF export.

Question 6

How do I analyze my shooting target?

Accepted Answer

Photograph your paper target, measure the distance between the two farthest bullet holes (group size or extreme spread), identify which direction the group is offset from center, and classify the shot pattern. Each pattern maps to specific biomechanical causes. You can do this manually with a ruler, or upload the photo to a tool like Shotalyze which automates the entire process using computer vision.

Question 7

How do I improve my pistol accuracy?

Accepted Answer

Track your shot groups over multiple sessions. Measure group size, identify your dominant miss pattern (low-left, high, scattered, etc.), learn the biomechanical cause behind that pattern, and practice the specific drill that fixes it. Then measure again to see if it worked. The shooters who improve fastest analyze every group and track trends rather than just shooting more rounds.

Question 8

What is CEP in shooting?

Accepted Answer

CEP (Circular Error Probable) is the radius of the smallest circle centered on the group mean point of impact that contains 50% of your shots. Unlike group size which is dominated by your worst shot, CEP represents your typical performance. It is used in competitive and military shooting and is a more stable metric for tracking improvement over time.

Question 9

What does my shot pattern mean?

Accepted Answer

Shot patterns reveal specific technique problems. Low-left (right-handed) indicates trigger control issues or recoil anticipation. High shots suggest heeling or lifting the head. Scattered groups mean inconsistent fundamentals. Vertical stringing points to breathing or cheek weld issues. Horizontal stringing indicates trigger mechanics problems. Each pattern has targeted drills that address its root cause.
