We missed target but it was because the client changed a major requirement half way through after they saw it working the way they originally requested. I believe that if that didn't happen we would have hit target. Another argument against up-front estimating and fixed cost projects. It doesn't take into consideration things like that. But to that point, really target + what it took to do the estimation. So an extra week + the money..
