OK you get 1K clicks from 5% of 100K uniques. Thats 1K clicks from 5K uniques according to my arithmatic which works out as a 20% CTR. In my personal experience and from figures that others have quoted here that seems like an abnormally high CTR.
I would have said that too, except last month I actually approached that number myself across a number of sites.
