How many completion % do you have in TPP?

[DANMATUS]

And how long did it take you? Did you farm it or did you just play the game? I just bought it on PC/Steam and just started, currently sitting on 3% completed. Not sure if its a massive project trying to get 100% completion but at least its something to keep me occupied till Vol 2 hits and I can move over to Old Snake. Also to be clear im talking about the completion % when you are sitting in the chopper, not achievements.
