If I may add, Mr. Chair, I'm trained as an economist and we have a good old joke in economic forecasting, which I guess could also apply to weathermen or other domains: Pick a number, pick a date, but never the two of them together.
I think the same challenges apply in the oil and gas markets. It is hard to predict with certainty what's going to happen despite the best minds and the best data. Things are constantly changing in the marketplace.
