I suspect that Project D (dollar value) would fixate on the dollar value for each story and submit themselves to a kind of "value paralysis" on a story-by-story basis; whereas, Project R (relative value) would be less concerned about that on a day-to-day, story-by-story basis. I believe that Project R would make more progress during an iteration (less fear), but that each project would be equally able to determine whether to continue at the end of an iteration.

I know there's more, but I don't know what more just now.
