Re: Staticstic app, ask for idea.

To integrate a calculated value with search features from admin app, I
don't know any other way than create and save a calculated field on
your model ...
This calculated field, you can calculate it with cube ... but if you
don't use the Cube for any other statistic than that, it is too much
overhead.
