Final Edit: Fuck it, I'll put up a vid. I hope it helps yall.
Quicker Cash farming in episode 1
Tip for farming cash (if you're not doing weight limit), during mission one on very hard you can cancel his gun fire by looking away from him. He'll only shoot when you get too close. It'll make you complete it in about 43-45 seconds. It's better than camping behind the dumpsters 5 times.
Edit: I should add a bit more information.
Everyone should know by now what the threshold is until Tokio starts firing his gun before running away. He'll shoot not at a fixed direction but where he last saw you (or where you last were before hitting that threshold). So cancel his gunfire in the middle or something, then cross the threshold either going left or right. Sometimes he won't even shoot pre-running but I haven't figured out how to trigger it. It could very well be possible to finish this without him firing a single bullet.
This method will always land you 43-45 seconds @ $544k, which is the most you could ever get I believe unless you glitch your way to the end of the level. I'm trying to hit 40 seconds but it's proving to be impossible lol.
Edit 3:
I made a picture to show where exactly the thresholds are. They're not exact but I'd say approximately sufficient.
Best thing to do is (and it usually is timed perfectly) to cancel his shot right near the threshold. Then cross it while changing your trajectory.
The red arrow is the exception. As soon as you pass the wall and see him, you're able to just walk along the middle. He'll always shoot to the right.
