Frame data for our game(s) are stored on a separate page under {Character}/Data ex Meta Knight/Data. This is so all the values are in one place and is meant to solve the issue of people updating the frame data on a character page, but not the frame data page.
We use two plugins: Cargo and Labeled Section Transclusion to achieve this.
Our Cargo usage has a template that contains all the frame data for a character that populates a database that we later retrieve values from on various character pages.
You can find links to these Data pages at the bottom of each character's page.
