“Figures from cars built” is the group of build years behind each row's MOT figures. Years where one generation gave way to the next can sit in a wider group until there's enough history to split them.

“Figures from” is the group of build years behind each card's MOT figures. Years where one generation gave way to the next can sit in a wider group until there's enough history to split them.
