The email read as follows:
For the 2017 season, AVP is adopting and implementing a modified version of the two rule trials that were explored in the 2016 Chicago event. More details can be found in the online Rule Book in Athlete's Corner.
- Match point freeze session/s will be in effect
- Let service will be allowed EXCEPT during the freeze session/s.
- A service replay will be awarded ONLY during freeze session/s.
In other words, when match point is reached by either team, the scoring will switch from rally to side-out, aka a team must be serving in order to score a point.
In addition, when side-out scoring is in place, let serves (when a serve touches the net on its way over) will not be allowed. If a let serve occurs, the server gets one re-serve.
