In the thread in P&WA on the issue of the oil spill, I expressed my skepticism that the rate of the spill could be accurately measured via analysis of underwater video clips. That skepticism was strengthened by the recent statement by Prof Steven Wereley, the originator of the first such estimate, that his earlier estimate was "consderably" low, despite his previous claim of a 20% margin for error. So I'd like to gain a better understanding of his method and if it is reasonable to believe it can be accurate in this case.
