Thank you, Mr. Chair. I appreciate the question, because there's as much art as science in the predictions. Indeed, it's a balance between the prudence and safety of having a prediction that you know you'll be able to meet and the desire to convey a sense of urgency and to convey to the team that we have to go as fast as we can. We're constantly balancing those variables, and sometimes we have erred on the side of being too aggressive, but it's always been with the best intentions to give the best guidance we can based on the evidence.
