Michael Cynil Parsons, the General Product Manager of tournament operator ESL, explained why the CS:GO IEM Rio 2023 final was played in a best-of-3 format rather than the expected best-of-5 on his personal Twitter page.

According to Cynil, ESL decided to change its approach to its championships earlier this year. As a result, finals of competitions that are part of the ESL Pro Tour Championship series, such as IEM Katowice and IEM Cologne, will be played in a bo5 format. The deciding matches of the ESL Pro Tour Masters series will be bo3.

The community has mixed feelings about best-of-5 finals

For many years, there have been numerous discussions in the community about the merits of best-of-3 finals. Critics have emphasized the huge duration of such matches, while proponents have suggested that it tests the endurance and stress tolerance of teams, as well as their map pool.

By examining the numbers of some of the recent bo5 finals played, it can be seen that the average duration of their broadcasts with four played maps was 5 hours and 10 minutes. If teams played all five maps, this figure would increase on average to 7 hours and 14 minutes.
