Hi, Playing against the clock is something that players must also learn or practice! That's another level of playing when clock is ticking, and you also have to take care of it. Another help of the clock is when playing against very slow opps, and we do not want to become rude. When both partners agree using the clock, there should be no dispute. Practically, yes, I think after a set period of time (in default it could be 7 minutes, but could set another quantity) the software could alert, and if within the next 1-2 mins we can't finish, it would make a new deal, and evaluate the party on a standard percentage rate (60-40 %?) as it goes on a real-life competition or tournament.
