Intro to the Exp't
This is my 9th part of the ASTRE project. There's only one exp't in which 2 Nagato class BBs with different levels will be tested on their day DA chances. In addition, data from the exp't will be used to estimate the FLoS modifier on CA(V), by comparing it with the previous exp't. 

Information About the Exp't
- Fleet & Test ship condition: - Enemy condition: - Test ship & equipment:
 * Morale <20 (severe fatigue / red face)
 * Ships are always beyond minor damage (小破未满)
 * Line ahead
 * AS+ achieved for every battle
 * No Saiun equipped
 * If both DA hit the enemy, they'll be counted twice (2=2). Scratches are not counted as hits.
 * Either Line Ahead or DL.

        - Flagship: Taihou lv 97~98

 - 6th ship: Maruyu ~ lv 30+

[ Exp't N ]
- Completed in 3 days

- # Battles & engagement form counting

- Fleet total LoS:  380 ~> 387  (+5% DA Chance)

Comparative Study on the Effects from Leveling (DA Chance)
Brief Conclusio​n:
 * Limited sample sizes (~300) give error ~4%, with 90% confidence.
 * In this exp't, Nagato Kai (lv 30~49) had 2.7% higher DA chance than Mutsu Kai (lv 96+).
 * As I made an assumption based on the previous exp't that ships below lv.60 will suffer from lower DA chances, this exp't report greatly countered that argument.

Comparative Study on the Effects from FLoS Difference (DA Chance)
Compiled with test results from the previous experiments. Brief Conclusion:

Do Double Attacks Increase Your Shelling Accuracy ? (cont'd)
As we can see from the chart, if each consecutive DA is counted separatedly rather than a set of attacks, DA seems to have higher accuracy (+6% when under severe fatigue) than single attacks.
