Mirage 4000 and 2000-5F's BR?

I have no idea why Mirage 4000 and 2k5f’s BR could be 12.7 and 12.3? any reason? I don’t think magic 2 and 530D can make these 2 planes stay at top tier, considering the CAS ability, M4K just 4 as30L and 2 gbu, no TVD pod.

the 4000 yeah is pretty mid to bad usually die because of the lack of countermeasures and having to use quite a bit due to the size what makes it worse is your forced to pop 4 countermeasures if you wanna use chaff , the 2000-5f though will only go up in june anyway because of getting micas
