I wanted to suggest a new function for the blog-statistics: show the date, when the blog had equal or less (equal or more) than one (two, three, ...) visitors a day the last time (maybe you could enter the number manually).
An example. Lets say the statistics are: 1 - 2 - 3 - 6 - 5 - 3 - 4 - 5 - 4 - 4. So the last time it had equal or less that 3 visitors is day 6 (after that it always had more). The last time tha blog had equal or more than 3 or more visitors is day 3. This tool would help me to estimate the minimum / maximum of visitors on the long run: "This blog never has had less than 5 visitors a day for within 5 month".
