Reading this table

Every number is ranked

Colour and bar show where a value sits inside that panel's own segment - its cell technology at its power class - not across the whole database.

Standout says why it matters

One phrase per row, generated from whichever metric is furthest from its segment median.

A dash means no data

The manufacturer did not publish it. We never estimate a missing value - the amber triangle marks those rows.
