The twist to the Knot story that I heard, and am hopefully remembering the details correctly, is that others prior to Olaf thought they had the Great Knots. I think they made the call to let others (including Olaf) know about them, but then later realized that the birds were not Great Knots. Instead, I believe they might have been Rock Sandpipers. At those extreme viewing distances, confusing a Rock Sandpiper for a Great Knot is understandable.
It was John that identified a Rock Sandpiper as a Great Knot:-

These birds are plainly a different shape in my view.
I am sure that they are close enough that both competitors will believe that some of the odder/briefer/non-photographed sightings made the difference.
All the best
