           Summary: Calculation of overall rating is misleading to users
           Product: WineHQ Apps Database
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: appdb-unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dimesio at earthlink.net


AFAICT, the overall rating for an app is calculated as an average of the
ratings submitted in tests for the most recent version. This leads to overall
ratings that do not match any of the submitted tests for that version.

The Microsoft Office 2007 installer is a good example:

Tests submitted on July 6 and 9 rated it platinum for 1.1.25, and the overall
rating was (correctly) platinum. 

A test submitted on July 14 rated it garbage for 1.1.25, and the overall rating
dropped to gold. 

A test submitted on July 16 rated it garbage for 1.1.25, and the overall rating
dropped to silver. 

This is misleading. The gold rating tells users they need one or more tweaks to
get the app working, the silver rating tells them that basic functions work but
some advanced ones don't; in the Office 2007 example, neither rating reflected
the data that was actually submitted for that version.
