On my site there is "Statistics of the lifetime and payout ratio of the HYIP".
The statistics is available at such parameters: "payout rate per day", "year of the beginning of work of the HYIP", "month of the beginning of work of the HYIP", "type of the script", "site languages" and "investment amount".
And also there is a statistics for some parameter (it is necessary to click the link with this parameter).
For example, you want to learn statistics for 2010. Then you click on the link "2010" in the table "Statistics of the lifetime and payout ratio of the HYIP(year of the beginning of work of the HYIP)".
Statistics is renovated with each new closed program.

I will be happy if this statistics is to someone useful.

For an example one of tables is shown here:
