It’s part of the Falcon’s legend. (And Han was always a bit of a B.S. artist.) That it’s inaccurate is beside the point.
But it feels like their just crapping on the original scene, and what it meant. I don’t think it should be part of the Falcons ‘legend’. Everything Han said in that scene was just talking up his ship to make it seem worth the price he would demand to fly them. Everything he said there should’ve been crap he pulled of the top of his head to fast talk this old man and this kid that needed a ship.
