Let my repost a post from a DBB flak thread I started long time ago

Ok, I tested my theory in the Guadalcanal scenario. I formed a bait TF composed of CA Chokai and E Yunagi ,having in total 11 DP plus several 25mm guns, and provoked the Allied CV TF to attack me. I added a small LRCAP group over my TF, but the group never broke through the escorts in the following air raids.
--------------------------------------------------------------------------------
Morning Air attack on TF, near Vella Lavella at 109,133

So I successfully fended off 25 and 26 bombers without a single bomb hit on my ships.
Now, I counted all DP and AA gun mounts on both ships. CA Chokai has 10 mounts, E Yunagi has 14 mounts. I do not know how the game code handles this, but those attacks probably ment the 25-26 aircraft were not enough to swamp my AA defences.In the ideal setup each such aircraft would face one dedicated AA mount firing at it.
Anyway, DP ammo is dangerously low on both ships after the two attacks.

I suggest you open Tracker and count all big DP guns on the attacked CAs and DDs. This may shed some light on the dismal result of yours.
Hope it helps.
