Clearly this proves that Kakashi becoming chunin at 6 years old was clearly retconned. As all new materials depict him being about the same age as everyone else during his younger years and in the chunin exams. Him becoming a genin at 5 and a chunin at 6 doesn't even make sense when even greater prodigies such as Minato became a genin at 10 and Itachi became one at 7 and didn't become a chunin until 10 years old. And even with the sharingan he got from Obito, both Minato and Itachi still outclass him. Logically, it was all definitely retconned.
