Hmm 6% of chapter 4 left? Have you seen the size of chapter 4? It's supposedly bigger than the previous 3 chapters combined and we all know how long it took him to pump out the first 3...Saying that there's only 6% of a chapter to finish isn't putting the actual size of the chapter into scope, it could 6% of rendering to complete (that shit takes a long time) or it could be 6% of code to complete (again that takes ages, especially if it's just one person) so how about you cut him some slack?
You also missed the point i was trying to make, he's the only one working on this so of COURSE it's going to take him ages to put out chapter 4, he doesn't have a team he can spread the load over to make things go faster.
Are you worried that chapter 4 isn't coming out as fast as you'd like it to? He gave the first 3 chapters out for free for crying out loud, that's more than what a LOT of devs dole out, usually it's just a few missions/scenarios with a demo of the game.
