Notes on these figures

Replace
Typical when chains are swapped AT threshold. If any chain on this drivetrain ever ran past its elongation limit, the cassette is compromised and the counter is meaningless -- flag it rather than counting.

Gathered by hand from manufacturer documentation, never scraped. Manufacturers change these figures and sometimes contradict themselves. Always check your own manual, and treat this as a reference rather than an instruction.
