It is calculated based on.

The azimuth error corresponds to an error distance deviating from the hitting area of the target 300 in the left and right directions while the trainee is tracking the target 300. The calculated azimuth error of each time point is displayed in real time on the azimuth display panel 122. The azimuth error may be displayed in an analog format in the azimuth error portion of the azimuth display panel 122.

The azimuth training score indicates the accuracy of tracking left and right while the trainer is tracking the target 300. The perfect score of the azimuth training score is 99, and the number of error signals is subtracted when the number of error signals in the left and right directions exceeds 14. For example, if less than 14 error signals occur during training, the final score is 99 out of 10. If n error signals exceeding 14 and less than 113 occur during training, the final score is 113-n. If more than 113 error signals occur, the final score is zero.
