No released values yet. The first edition draws the history here with its interval band and class bounds.

The line is the point value by edition; the band is the 90% interval; dashed lines are the class bounds at 2, 3.5, 5 and 6.5.
No movements yet. Changes since the previous edition are listed here from the second edition on, with the indicators that drove them.
