Reading this graph:

Each line shows the scaling trend calculated from available data. Note that this is a statistical approximation and may be slightly inaccurate for specific scores. Scores below 20 are modelled separately and not shown. The grey line shows scores if there was no scaling and is useful to see if a subject scales up or down.
