Total aircraft shot down= Percetage kills + Fixed kills. If a setting has a percentage kill of 67% and a fixed kill of 7 aircrafts, and encountered a 20-plane slot, it would shot down 20*67% + 7 = 13+7= 20 aircrafts. (in other words, this slot is wiped out.)

Now think about this happening to 24 slots. By one destroyer alone. WTF?

If speaking about number, stated in this table, 67% is trigger rate of aaci, not percentage shot down.

I calcuated it now, and seems that Teruzuki shoot down  nearly 30% of the slot in proportional formula. Alright, I went to check the wikiwiki. And you are right, 67% was not the percentage kill, the percentage kill was around 55%.

Akizuki w/ HHR config gives 221.7 adjusted AA, so it gives 199/360 (after all the flooring, rounding, etc.) proportional kills, roughly equal to 55.3%.

Now, proportional kills have a (estimated) 50% chance of success, just like fixed kill, so if AACI succeeds on a single Akizuki w/ HHR, in line ahead:

25% chance of 55.3%+ 23 aircraft ((221.7+12)/10＝23 fixed kill, regardless of the slot size )+1 aircraft shot down

25% chance of only 55.3% +1 aircraft shot down

25% chance of 23+1 aircrafts shot down

25% of only 1 (minimum guaranteed kill) shot down.

In other words, as long as AACI succeeds, any slot with less than 24 planes have 50% chance to be wiped out, and another 25% chance of losing about half of its aircrafts before having any chance to attack.

Compare Operation Ten-Go with a certain Niconico test video, AACI is approximately 2500 times more effective than real life WWII AA fires, or around five times the effect of an Arleigh Burke-class destroyer (since it carries 90 missiles). Non-AACI fires are also around 5~10 times more effective than their real life counterpart.

The fixed kill bonus of 7 didn't mean only 7 will be shot down in this part, my mistake.
