Yes I think it was an interesting use of statistics. I am sure the 
failure rate of big bells is miles higher than that. Everyone knows 
that. The failure rate of smaller bell clappers is largely irrelevant 
as they hardly ever break. I know a few years ago when all the 
experimentation was going on, our tenor at Newcastle got through some 
clappers in a very short time. Similarly Grantham did the same etc 
etc. I remember at Newcastle one night when the ball came loose on the 
shank but didnt break or fall off. The thing sounded like a bag of 
coins being dropped on a metal surface.
