Where 51% Shows Up in Real Life
Simple majority. 51% is the minimum needed to win a vote, pass a resolution, or control a company. In deals, "more than half off" triggers urgency.
Once a discount crosses 50%, the "deal perception" jumps dramatically. 51% off feels meaningfully better than 49% off, even though the difference is just $4 on a $200 item.
