Percentage Pass Percentage Fail

I asked before about creating user friendly interfaces for the end user and for the most part I was successful.
I used scripts and AQTestcase to give a nice summary to the user.    (Yes I am learning Python on the fly)
The users want a little more.
Summary Info
Test Cases Run

Test Cases Completed

Test Cases Failed

....................you know where I am going with this.
I am researching Ready API but it seems it is more for performance testing.

Any suggestions would be very much appreciated.
