Decks with a low match count will be ignored here
You read from left to right the intersection point means the win rate vs the vertical deck. The small right corner number corresponds to the number of matches. Every deck performance has also a performance interval, for that calculation it's used a binomial proportion confidence interval with the Wilson score interval at 95% confidence.
Some tournaments will include only the day 2 complete and others will have more.
