The original article didn't have that plotted, but I don't see why it wouldn't follow this line fairly closely.
I'd be more interested to see a graph of the proportion of outside-of-the-box shots scored over the years. Has it gone up, because people are only taking good long distance shots now and fewer random potshots? Or had it gone down because good players mostly know to avoid them and bad players are bad at scoring them?
Yeah these are all interesting and I'll follow their development for sure, as I know there were a lot of talented people that worked on DE. But I would be hard pressed to call anything a true "successor studio" without any of Kurvitz, Rostov, Hindpere and Tuulik - and preferably all four of course.
