Okay~ I don't know if this will help, but regarding the 4-5 set-up, I use the 2FBB 2CA 1CAV 1CV build and use the middle route that goes through the submarine node. Took me around 6-7runs for 5 kills. Experimented with using Zuikaku Kai2A with max chevron planes (dive bomber on 1st slot, 1 +10AA fighter, 1 +12AA fighter, 1 saiun on smallest slot) but it was insufficient for AS, so it seems that you can only use Kaga if you use only 1 CV.

Disclaimer #1: Level of ships ranged from lv 80 to lv 125. (The lv 125 one is my waifu who is an FBB.)

Disclaimer #2:  I can't comment if the yasen route works  because I tried it once using 5BB 1CV and failed terribly. It is rather risky since you have black ri shooter and you have no space for yasen equipment.
