-- Slot 2: Alice gets her first choice, Bob gets his 2nd choice. Even though Bob gets a worse score than Alice in the second slot, Alice’s aggregate compromise is higher. This is because she was given her 3rd choice in the first slot and we consider one 3rd choice worse than two 2nd choices - refer to the slot compromise formula under the first expanding more+ section (under the Compromise heading).
