In a Swiss tournament, all the results of a particular round need to be recorded before the next round may begin. This means that each round will take as long as its slowest match. In a single elimination tournament, any game may commence once the two proceeding games that feed into it have been completed. This may result in one branch of the bracket falling behind if it has several slow matches in a row, but it may then catch up if it then has several quick matches. Additionally, each round has fewer matches than the previous, and the average longest match in a round will more closely match the average match as the number of matches in that round decreases.
