The table bottom right shows a clear trend: as boys were older, they were afforded progressively higher strokes per incident. Only 46% of 11-year-olds received 2 or more strokes, and this value rose consistently to 16-year-olds, who received 2 or more strokes 94% of the time. The same trend can be seen in percentages of 3+, and 4+ strokes per age.
Notice also that serious offences only began to be met with 4 or 6 strokes at the age of 13 or higher. From 14, any incidence of truancy, for example, brought 6 strokes, whereas the few examples of this for younger boys attracted more lenient treatment.
