@Homuhomu123 You might want to confirm your test again. p "20.3cm + 12.7cmHAFD + 90mm + AA radar" is actually classified as "B.B.R", or "Built-in + Built-in + Radar", api value 5. < You said 20.3 cm is not matter in the pattern to change from H.C.R to B.B.R meaning 12.7 cm HAFD and 90 mm make them B B.R? That is weird for 2 reason First even they can do cut-in (considering AAFD upgrade) they are still Normal HA. So if they equip along with 12.7CMHA+fd 90 MM + 25MM CON +radar they are treated as H.C.R < 2. 90MM haven't been tested so you can't even tell the pattern. From my understanding the main gun is the problem here not them. If you want to fix, please explain in details
 * Special HA mounts with built-in AAFD, (Akizuki Gun;  12.7cmHA+AAFD;  80mmHA), are always treated as ordinary HA mounts on Akizuki or Maya Kai Ni
