The media constantly says that X is 30 times less than last last year, or 11 times less than Monday. What does that mean ? How does it translate into reality? How is one to calculate such a figure?
Why don’t they say 25% less or any percentage if that is what they mean?
I have seen academics use this phrase and I have written to some and asked many people who should know and I have never received an answer.
Could it come from some discipline like Chemistry or physics, or some other culture?
