What you said there was exactly what I was wondering, too.

According to multiple reports from players, the old AA formula posted on combat page is no longer giving consistency.

As for the "only 7 plane" statement, you may wanna check this



The latter one with numerous dots it is. Test map 5-4-C.

The red dots represent %shot down when Air Supremacy, while blue one shows %shot down when Air Superiority. The test was carried out last summer before AACI was introduced, thus may not be fully convincing.

As for your question on why Nu cannot be disabled without AACI, well... I cannot answer but to guess, normal fleet AA are like doing division but barely zero out something, but on the otherhand AACI is like doing subtraction.
