Turbo Mode is the fixed-court version above. Your four stay on one court and cycle through the three pairings, then the courts remix. Because a court’s next game never depends on the other court, a court that finishes early locks its score and starts playing again immediately.
Courts only sync at the remix, where the next game genuinely cannot be known until everyone is in. Standings come out the same either way, so finishing first is not an advantage in the results, only in time on court.
It is a toggle when you set up a session. Eight or nine players, Classic for full mixing, Turbo for no waiting. The rest of the event runs the same.
