Has an Olympic Hockey (Women) game ever ended 5-3?
Exactly once. On February 11, 1998, Canada beat Sweden 5-3, and no Olympic Hockey (Women) game before or since has ended that way. When it happened it was a scorigami, the first 5-3 in league history.
That makes 5-3 the 27th most common final score out of 41 that have ever occurred in Olympic Hockey (Women). One point away, 6-3 has happened 1 times and 5-4 has happened never.
