Question: what is the formula to calculate the number of matches in a single league tournament?
Answer: To determine the number of matches use the formula, N=(cx2)-2. For example 17 participants/teams times 2 equals 34 minus 2 equals 32 matches. And there is a possibility there could be 33 matches if the loser bracket participant/team makes it to the final and beats the winner bracket participant/team twice.
