OK.
Doesn't change much.

Except that in that time 35,000 to 175,000 more barrels of oil have leaked out.

Yah, but it's still a small fraction compared to the big spills, that's my point.

Maybe not:

" The U.S. Coast Guard has estimated that oil was gushing from a broken pipe on the Gulf floor at the rate of 5,000 barrels a day.
But sophisticated scientific analysis of seafloor video made available Wednesday by the oil company BP shows that the true figure is closer to 70,000 barrels a day, NPR's Richard Harris reports.
That means the oil spilling into the Gulf has already far exceeded the equivalent of the 1989 Exxon Valdez tanker accident in Alaska, which spilled at least 250,000 barrels of oil.
The analysis was conducted by Steve Wereley, an associate professor at Purdue University, using a technique called particle image velocimetry. Harris tells Michele Norris that the method is accurate to a degree of plus or minus 20 percent. That means the flow could range between 56,000 barrels a day and 84,000 barrels a day.
Another analysis by Eugene Chiang, a professor of astrophysics at the University of California, Berkeley, calculated the rate of flow to be between 20,000 barrels a day and 100,000 barrels a day. "
