Oil Spill Recalculated

So I was reading an article in the NY times about the estimations of the oil spill. And it said that the estimations were inaccurate and everyone is criticizing BP for their measurements. Okay? With this new information, the government can do what? There are no huge disadvantages to not know exactly how much oil was leaked. So can you please stop getting angry, and worry more about the actual problem at hand, the oil spill!
