This match is considered a tie even though the scores differ by 6 points. With 94 decisive rounds (Rounds not ending in a tie), that gap is not large enough to be statistically significant at 90 % confidence.

At this sample size, any difference below 12.4 points can still be explained by random chance rather than player skill.
