  • Confirm the active rifle, ammunition or lot, projectile, and profile name.
  • Confirm distance, angle, velocity, pressure, and sight-height units.
  • Confirm zero distance and that the rifle still holds its mechanical zero.
  • Confirm muzzle velocity belongs to the current ammunition and barrel configuration.
  • Confirm the coefficient is paired with the correct G1 or G7 model.
  • Confirm density altitude or station pressure authority, temperature, humidity, and update time.
  • Confirm target distances and compare more than one solution row.

If: Only one row looks wrong.

Check that target's distance and identity first. A single bad row is weaker evidence for changing a whole profile than a repeated trend across distances.

If: Every row changed after an environmental update.

Confirm which atmosphere source became authoritative and whether the workspace accepted a new solve. Compare source, timestamp, and density-altitude or station-pressure semantics.
