There are a few instances of separate developer / project accounts across the different categories. I thought about adding them together but I don't know enough about who does the actual work for the projects to make any decision. Leaving it "as is" was also less work on the end results.
I think that the distribution of rewards is actually a pretty good shape. No user is miles ahead. There's a good spread with a large number of users are getting some very solid rewards. I'll draw up the distribution at some point to illustrate. My guess is that it compares favourably with that of Steemit as a whole.
