This is the first challenge that having the skill from completing it once doesn't really help for Ultimate rank. The skill is more for situational momentum recovery and in this one you won't likely hit the 32 seconds or less if you get in a situation where you hit the ground and roll. The wall run up the building is where it's trickiest because if you press too far one way to adjust you end up running sideways. Also, never try to zip up the building at the end unless you're running straight up it or you'll likely end up going sideways. You have to press the opposite direction to correct your run if you go sideways. It’s very hard to hit the minimum 32 seconds for Ultimate rank if that happens. https://store.playstation.com/#!/tid=...
