Potential Spoiler ****

Not much to this Trophy, Other then it's best to do this on NG+ since you can skip every CS. and you get (Clear) bonus items that help - and you will have left over ammo from 1st Playthru to let you Zip thru the chapters.
you need to aim to clear EVERY Chapter in under 20 mins. with skipping CS and not wondering around, you can clear CH 1~5 in 1 hour. I managed to do CH 1 in 13 mins, 2 in 12 mins 3 in 13 mins Ect.
Chapter 6 7 and 10 will be the time sinks They are the ones with the most "non Skip able" Clips.
6 an 7 took around 40 mins - I can't Recall witch one of these two were the longer one, w/e has you going to the *Curch* with about 3 boss fights will be it.
chapter 10, Sprinting thru / past everything, and Killing the 2 bosses with in this chapter took me just shy of 40 mins)-
Currently on Ch11, and just barely 3 hours of play time in.
Another thing to note. is Deaths, The Fewer the deaths, The More time is shaved off your "tottal" I did a run in 7.5 hours (Forgot were to go in CH2, and saw a Extra CS for a Troph - with 20 deaths, it took 1 . 5 hours off my time as well as avoide going to the "hospital" were you get your upgrades, unless it's story related, can easly spend a hour there thru out the game, unintentionally
You Will most likely Lose 1~4 Lifes to the "Lock box" near the end of the catacombs, - that just seems random you can go 1//1 or 1/4
