Disclaimer
This post is used for saving experiment data from other Kancolle testers, on the trigger rates & effectiveness of AACI (Anti-Air Cut-In). For a higher level of objectivity, I will not conclude or formulate anything below. In order to help readers understand the exp't, I added parts "Explanation" & "Simplified Test Results" according to my understanding of the experiments (therefore you're welcome to evaluate my work & translation).

Since the following tests are all about probability, data from smaller sample sizes would be surrounded by parenthesis, which indicates less reliability. For more information on its significance, please visit Calculating Confidence Intervals for Underlying Probabilities by Winzongod.

Since some pictures below were downloaded from websites with no explicit citation, please contact me if you know any of the sources. Also, if you consider any unauthorized using of exp't data, you'll have my apology and associated content shall be deleted immediately.

If you noticed an error on my translation, ambiguity in the language, any important info were missing, or just need help with anything, please leave me a comment. I hope the following info will be helpful.

N - Categorization of AACI Type & Comparison
'Exp't name: 'VARIOUS''

Explanation: (from Jifaru)

By reading network traffic (API data), it shows that the game currently recognizes 12 types of AACIs and identifies them as API_1, API_2, ... API_12. It is also tested that each AACI type shoots down a fixed number of planes in every slot in addition to the random planes that you will shoot down through normal fleet AA mechanics.

Furthermore, only 1 AACI may trigger per round of combat.

The highest API number AACI tiggers over lower-numbered AACIs. Basically, if you are running multiple AACIs, the highest API rolls first. If it fals to trigger, it goes to the next lowest AACI., so on and so forth.

Generally speaking, higher API AACISs are weaker than lower API AACIs... (Click here for more explanation).



I - Fleet Total Anti-Air
Exp't name: 対空カットインその４

Blog / Author: 艦これ-チラ裏検証- / by くうぼをきゅう

Exp't Date: April 12, 2015

Explanation:

2 fleets with huge differences in fleet total AA stat (445 vs 134) were sent to 1-4. Whenever an enemy carrier appears, relevent data (morale of Akitsuki, #plane shot down, AACI triggered or not) would be recorded.

Using formation line ahead, kept advancing until taiha'ed. Sortie again when fully repaired &/or morale recovered. Also, there's a total of 4 slots of enemy bombers (dive + torp), whenever their CV is present.

Only Akitsuki (placed as non-flagship) is equipped with AACI setup (10cmHA x2 + T13RK). Thus all data below pertain to Akitsuki.

II - Individual Ship's AA stat & Various Setups

<p style="color:rgb(0,0,0);">Explanation:

<p style="color:rgb(0,0,0);">Similar fleets with exactly the same total AA were sent to 1-4. Whenever an enemy carrier appears, relevent data (morale of the test ship, #plane shot down, AACI triggered or not) would be recorded.

<p style="color:rgb(0,0,0);">In the first part, 3 DDs (Kagerou, Ushio K2, Akitsuki) with very different individual AA stats were tested and their AACI rate / effectiveness compared.

<p style="color:rgb(0,0,0);">In the second part, Akitsuki with different AACI equipment would be tested and their AACI rate / effectiveness compared.

<p style="color:rgb(0,0,0);">Using formation line ahead, kept advancing until taiha'ed. Sortie again when fully repaired &/or morale recovered. Also, there's a total of 4 slots of enemy bombers (dive + torp), whenever their CV is present.
