Just looked at the trophies and holy shit, that platinum looks hard and a lot of work. Not sure if I'm gonna try for it
The 70% Shot Accuracy will be a massive pain. I'm not sure if you can check how accurate you have been so far, but it would be extremely annoying doing a 70% Accuracy attempt and not getting the Trophy.
It's going to be about 4 playthroughs for me before I get the Platinum:
First playthrough on Moderate difficulty, not focusing on getting all of the collectibles
Second playthrough on Crushing difficulty
Third playthrough on Easy, focusing on getting at least 70% Shot Accuracy
Fourth playthrough for the speedrun Trophy
