Here is an overall and team by team analysis of the break point phase from 2019 VNL. The overall break point rate of 32.1% is essentially the same as all major events / leagues.

The ATT/D (attacks per defensive opportunity) is 42.5, which is also in the ‘normal’ range.

Below is the ranking of teams in different areas of the break point phase. Using really simple analysis, break point percentage has the same influence on win percentage as sideout percentage. Interestingly, ace percentage is completely irrelevant, and block percentage not particularly important. The areas that do show influence on win percentage are ATT/D and transition attack percentage.

Wow! Great question.
Thank you for thhis
