Thank you Alec for making this thread. Appreciated.
Having said that, 0:52 is overrated* and here's why: I got a 0:37 quitout on SA with no boost. Now remove the time lost from destroying the first alarm, add in 2.x, 2 boosts till the lockshot, and TBT (Tower Boost Trick - you shoot a bullet at the first tower from afar to lure the guard for a boost. This has worked for me on SA and while it obviously has lower chances of working on A, it should still be possible). I thought 1:16 was a chimera but I was wrong (was getting boostless 1:16 paces thanks to the amazing GWT (gate warp trick)) and alarms aside the only real difference between that and 0:52 is needing insane luck for at least 2 boosts, or preferably 3. This is just my analysis because I've never played Dam Agent in 50 years but from my experience on SA I have renewed hope in the "impossible 0:52". Healthy runs should happen once every few hours, which isn't bad compared to mindless Depot A warps that happen once every 10 hours.
* it's insane but not as insane as people who are clueless about the level make it out to be
