Keep the target image honest

I save one full photo before I crop to a group. The full sheet shows the target, the conditions of the paper, and whether another aiming point could be confused with the group I want to measure.

The analyzer can find likely impacts, but I still review every marker. Torn paper, splatter halos, pasters, and printed graphics can all look convincing to a detector.

Measure the same way every time

A group size needs a known scale and a defined measurement method. I use the same target reference or ruler, check the selected impacts, and keep the result connected to the firearm, ammunition batch, and distance.

• Confirm the impact count
• Set scale from a known printed dimension
• Keep called shots in the session note
• Compare like distances and conditions
• Repeat promising results before changing the plan

Let the record earn the conclusion

One target can be useful, but it is not a verdict. I treat a result as a reason to repeat a controlled test, not a reason to rewrite the recipe from memory.
