I never cake times. Almost all my pr's are results of 5-10+ hours of playing. That 58 on SA took about 8 hours to get even though i was mostly aiming for a 59.
Edit: Im extremly near to give up this level after those events:
Had a run that was really nice and i was just hoping "come on Doak, Be there now". To my suprise, He was there!
Everything went fine until i was gonna throw the first mine, Of course i miss it(Right strafe sucks)!
I keep playing while hating myself for that and then like 20 mins later i get one of those runs again where Doak is there. I hated myself so much from last time i was determined not to @#%$ it up this time. So i pause in front of the door, Gets boosted like a meter away. Of course i thought, No problem, Just a little bit of right strafe and then decode it.
So what happens? As i press "Z" i get backboosted...Of course game doesn't react to my button pressing. I run back again and press "Z" again...Backboosted again!
Cavs 00A was a breeze compared to this...
