I haven't used Rally but, just thinking : since it was a story you worked on, there's a high chance you have added some comments on it, or possibly even created it yourself.
Is there a way to use this in your query?
For eg - [CommentBy = Adarsh Kumar], or [CreatedBy = Adarsh Kumar]
I use Rational Team Concert, and this may be a problem there too. If one modifies the design where you have a Dev owner, and a FVT owner, and give the ability to query on these two separate fields, it would be easier to track efforts at the end of the year eh? ;-)
