I'd argue that it's just as easy to get multple stacks from the landfill as it is to get multiple stacks from the HP station. Its level of difficulty scales with how badly an alliance shoots itself in the foot by mucking up the orientation of totes before the landfill bot gets to them.

With the right design, the right sensors/automation and some practice, I think it's plausible for a single robot to get all 18 upright totes on the landfill in a match.
