As a very senior developer by some measures, I always put a strong emphasis on what's not going well. What's broken can be fixed, as long as it's known. I also believe that it's better to undercommit than overcommit. The delta between committing to and then achieving X+Y vs. committing to and then achieving X alone is fairly small compared to the other alternatives. Commit to X and achieve X+Y? Big positive reaction. Commit to X+Y and achieve only X? Even bigger negative reaction. Why put yourself in a neutral/negative space when you can put yourself in a neutral/positive one? It kind of feels like sandbagging, but I've seen it work well for all concerned too many times to do otherwise.
