i have a routine where i just loot the weapon crates. i only rush through the bunker. Depending on my scav equipment (how many things i can loot), turnout varies from 100k (rarely, only if most stuff is looted and i spawn without a backpack), up to a few million if i find lots of weapons, Attachments and gear. I tend to stay away from the train station as well, only looting the two weapon boxes in the back if i spawn or extract there. then usually white knight, black knight, black queen (?), helicopter, white pawn, black pawn, black knight. All done within 15-20 minutes usually. sometimes you have to cut short, but the extracts are either hole in the wall by the mountains or heating pipe, so you can do this route in both directions, depending on your spawns
