- If you view percent as a mathematical operator meaning 'divide the previous
- number by 100', then sure, your point stands. But, it's been my experience
- that people tend to reserve percent to mean 'some part of a whole', and
- when you deviate from that use, people can sometimes become confused.
-
- Communication was the point of my note, and in the interest of
- communication I've found it helpful to reserve percent only for those
- cases when I'm describing some part of a whole. Come now, is communication
- really enhanced by saying "A is 400% the speed of B", rather than just
- "A is 4 times the speed of B"? Some people I know would be confused by
- the first statement.
