NOTE: As mentioned before, these calculation only serves as rough estimates on your ship's artillery spotting chances. More credible tests (#ATK > 170 for p > 70%, while #ATK > 256 for p < 60%, minimun) are required to come up with a better formula. Deviations from actual test results are supposed to be less than 5%, otherwise reworking on the formula itself could be considered. This does not include effects from HP status(小破・中破), and undetermined factors like formation & special ships / maps, etc. The estimates on which the true probability is closer to 50% will be less accurate.

- Although it is still uncertain that if using 46cm triple on non-Yamato class BB would affect their DA/CI accuracy, you may consult the following link as reference: [http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Accuracy_Test_Results_(Source_to_be_cited)#II_-_Preliminary_Test_on_the_Overweight_Penalty_.28SOURCE_UNKNOWN.29 Preliminary test results on the overweight penalty] (source unknown)
- [http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Accuracy_Test_Results_(Source_to_be_cited)#II_-_Preliminary_Test_on_the_Overweight_Penalty_.28SOURCE_UNKNOWN.29 Preliminary test result] shows the '''overweight penalty''' ''(eg. using 46cm triple on FBB)'' could somehow lower shelling accuracy from single attacks. It is suspected that this would affect Artillery Spotting, too. However, the penalty could be largely offset by leveling (married ships), high morale ([http://kankoreshuukai.blog.jp/archives/2474494.html as high as possible]), and using 35.6cm (no variation).
