→Artillery Spotting Trigger Rate Estimate: (Beta ver.)
NOTE: As mentioned before, these calculation only serves as rough estimates on your ship's artillery spotting chances. More credible tests (Sample size > 170) 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 should be considered. This does not include effects from fatigue, HP status(中破), and undetermined factors like formation, level differences (>>10), a few special ships (esp. CA) or maps, etc. The estimates for which their true probability is closer to 50% will be less accurate, and vise versa.
