@ Godsime-senpai, i am fully aware of the captain stats...and how poorly inaccurate they are compared to what is shown in the manga/anime...case-and-point...Aizen and Yamamoto...if the stats were to followed to the letter, they would be equal in power, yet Yamamoto grossly outclasses him in spiritual power, sword skill, Kido, etc, etc...even Kisuke outmaches Aizen in some aspects...so i based my idea on their shown battle prowess and records.

And the term above captain is to represent the skill level that stands above the base of captain...there is no upper of course...but by comparing characters, you can see the power differences.
