Much easier in a group, even just a duo. Try checking SteamCharts for low peaks of active players.
We bounced around the map going from the top to the bottom and back and forth in case any other players were trying to crash our party.
Also probably want to bring a fire turret and throw that down when you're extracting in case anyone else wants to try cutting your rope.
You'll still get credit for the extraction even if you're downed when the helicopter takes off.
