They said the plume was magnitude 8 and had a narrow, vertical and less dense part, which was only visible for a few seconds, and a wider, more dense part that lingered for a longer time. Since the Centaur created a nice crater, they speculated that the ice wouldn't be a solid surface. Overall it fit their models, it just didn't display much over the crater rim.

The 100kg figure would be based in what LCROSS could see from the plume, not the whole plume.

They said also that the analysis from the telescopes was going to take a longer time because their signal vs background wasn't so strong and, if I understood it right, that they have seen changes in the surrounding terrain due to the materials coming from the impact.
