Speculation based on observation here, but it seems that the thing that hoses you in 4 man groups is missed mobs that don't get killed fast enough in combination with the seemingly lowered oxy droprate not making up for the higher number of mobs.

Several times the whole room was empty, until some final runner sitting under a stair or in a corner got killed, and then a whole new group spawned.

Keep moving, use enemy radar, don't camp spawns (but feel free to stand outside the doors.
