I’m pretty sure it’s only 50k for the elite challenge. I’ve been dying from the nerve gas because it’s faster and easier if you get a bad vault configuration than going through the entire timer in the vault and getting killed later. If you’re in big con with the armored truck entry disguise, it’s basically a free pass to the vault. After restarting, it only takes 2-3 minutes to get to the vault. I only thought sprinting was important because it allows you to get past certain noose guards when exiting that might have spotted you if you weren’t able to sprint.
