How does an observer determine the average deviation when conducting registration?

To find the average deviation when conducting registration, the method involves taking the total deviation observed and dividing it by the number of rounds fired during the registration process. This calculation provides a measure of the consistency and accuracy of the fire. The average deviation helps the observer understand how much the impacts of the rounds deviate from the intended target, allowing for adjustments to be made for future fire missions.

Dividing by the number of rounds gives a clear assessment of the overall pattern of accuracy, reflecting whether a systematic error exists or if the rounds are generally in alignment with the target. This average approach is essential in artillery operations, where such deviations must be minimized for effective targeting.
