So let’s do the math. New gear map is 15 stages at 16 nrg per, or 240 total. To make the math easier, assume you’re at level ~123 with 80 nrg. That means 3 refills of your nrg to run the roadmap. You start at 6am, You run the 1st 5 stages to consume your nrg. To make things simpler, nrg reload it 1 point every 5 minutes (it’s actually worse unless you have the appropriate territory), so 12 per hour or 6 hours and 40 minutes until full nrg. At 12:40, you run the next 5 stages, and again wait for nrg reload. At 7:20pm you run the last 5 stages. Let’s assume you don’t wait for reload, but use nrg as available. To get the necessary nrg for tomorrow, you need to stop at 11:20pm. That means you can get 8 runs of 13.3 or 16 runs of 7.1.
If any extra roadmaps are up, or you want to repeat any stage, adjust the numbers appropriately, and start to pop open world cans.
Good luck farming enough survivors, shirts & gloves (for the endless level ups) and weapons if you are dedicated to running the map.
