Live, modelled, counted: the grades a figure wears

A figure marked live was counted, and the page says when it was counted. A figure marked modelled is the register's own arithmetic on figures it can show, and the working is printed rather than asserted. Nothing important is published without one of those two marks.

Worth today is the clearest example. It is modelled: the register's new price for the exact variant, moved by age and by kilometres against the norm for that class, with the yard's actual closes and the state's on-road rules set beside it so you can see what pulled the number.

The grade exists so you can decide how much weight to give a number. A modelled figure is a good starting point and a poor last word; a live one is a fact with a date on it, and the date matters as much as the fact.
