To look first at the situation down here in the run-up to 1987, I was always pretty clued up about MGS. So, the figure of 25 canings across the whole school in my time there that I posted some while ago here still strikes me as accurate.
However, let’s assume I was not quite as street-wise in my first two years and exactly that number again slipped under my radar. That’s still a mere 50 canings in 7 years. Average 7.14 a year and I think that was, for a school of c 750-775 eligible canees(VIth form excluded)about par for the course for the time, giving you a less than 1% chance of touching your toes in any given year.
