Why did we all get it wrong?
*To fit the parameters of the black hole orbit we need 5 well-timed maxima.
*The outbursts in 1948, 1960,1972, 1983 & 1994 seemed to fit the bill.
*The 1994 outburst was the best observed one ever and tied the model down very tightly.
*But, suppose that the 1994 outburst was a mistake?
