Bleach Wiki talk:Statistics

Quick Questions.
I was just wondering if anyone could tell me when these particular points were stated, thanks in advance.

Retsu Unohana ■Is the second oldest captain in the Gotei 13.

I figured she was the second oldest I would just like to know where it was stated. Byakuya Kuchiki ■He is the third youngest captain in the Gotei 13.

This sounds right, I just wished to know where it was stated.

■Is one of the most proficient combatants in Soul Society excelling in Shunpo (presumably only second only to Suì-Fēng) and Swordsmanship and Kidō.

I thought that Kubo's stats had Yamamoto as faster than Byakuya?
