Throws scored 2-7 points depending on amplitude + landing; Ippon (full throw to back): 7 points; Wazari (partial back-landing): 5 points
Why people argue about this
People often assume that just because a throw lands perfectly with the opponent's back facing them (Ippon), it automatically scores 7 points without considering other factors like amplitude or how hard they threw it. But actually, the rule states throws score between 2 to 7 points based on these specific criteria, not solely by whether it's an Ippon.
