Other observations:
The vast majority of entries are for an individual or small group participating in the same offence. However, there are a few instances where a larger proportion of a particular class was caned, usually for failure to do assigned work or insufficient effort in the same. One example had nine 15 year old students, all from the same room, receiving 2 each on the seat for exactly this type of reason. I have not noted any entry caning an entire classroom.
