The new information is in the distribution parameters that were updated based on the Mt.Gox data.
The Mt.Gox leak was the data after accounts were frozen right? Considering there were many hints of Mt.Gox's impending failure well in advance (goxing was a verb a long time ago), I expect a large percentage of people withdrew their funds either completely or mostly (my case). Therefore, I am not sure how useful raw Mt.Gox numbers would be for finding the overall distribution.
