I think you're looking at the X11 LeaseRig. The different "greens" are a little hard to distinguish on the graph to the left. If you look at the other graphs, you can tell that ScriptGuild is doing about as well as Clever/Waffle.
You're right, these greens were too similar. I changed LeaseRig X11 to a light shade of blue, this should be less confusing. Thanks.
