Controlling gun stability
Dev X
Standard deviation of the aiming point at the last second in the -axis direction.
The closer Dev X and Dev Y values are, the better.
Dev Y
Standard deviation of the aiming point at the last second in the -axis direction.
Aiming accuracy
COG
The simulated target redrawn by the system corresponds to the actual target; represents the accuracy of the aim.
The higher the value, the higher the accuracy.
Trigger control capability
RTV
The relative value of trigger pressure is calculated as the ratio of the distance moved by the gun 0.2 seconds before firing and 0.6 seconds before firing. If the distance is less than 1, it indicates that the trigger instant movement is less than the average value.
Indicates the cleanliness of the trigger.
ATI
The absolute value of trigger pressure is calculated as the absolute distance of muzzle displacement 0.2 seconds before firing.
Low value, stable muzzle. Large value, obvious shaking.
TIRE
The average falling point of the aiming point is closest to the target center, 0-0.2 seconds before firing , 0.2-0.4 seconds , 0.4-0.6 seconds .
The higher the score, the more decisive the shot, and the better the timing.
