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.
