In terms of convincing, the latter test I linked you serves as a better example. The author ONLY equipped two guns (three for the CL only test). The above chart had other random variable of ASW, Radar T21, rocket launcher,  mini sub, and Seiran. The above chart you believe to be more convincing had other accuracy equipments involved in the test. Thus, we couldn't approximate the actual data of accuracy of guns alone.

Your purpose of the study is the accuracy penalty identification of main and secondary guns right? not guns + bonus acc equip.
