Statistical Tie

This match is considered a tie even though the scores differ by 4 points. With 96 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 12.6 points can still be explained by random chance rather than player skill.
