I see three things to accomplish a timely finish but still allow players to play 1P.
1. Shot clock.
2. Grady rule. This will eliminate the large wedges.
3. In a race to 3 allow three hours, in a race to 4 allow four hours. After that its one ball one pocket.
That should take care of all the slow play.
I agree with all of this. The only thing(s) is...
- A shot clock requires one tournament official or volunteer per match
- Players who are out of TD supervision range might be inclined to mutually "forget" to spot the extra balls if they are traditionalists
- Going to 1B1P requires sufficient monitoring by the TD staff to make it happen in a timely fashion
The bigger the event, the tougher these three rules to make efficient use of. So for DCC these would be tough, but most other tournaments it might work. There would need to be an investment in dedicated shot clocks in my opinion, because the phone apps are not really visible enough, plus they are -- well, most likely someone's phone lol -- and calls come in, etc, etc.
For smaller events, this 1-2-3 approach probably works beautifully, as long as the TD staff is committed, and they recruit the same number of volunteers to be on hold that they have invested in shot clocks, and given them the necessary training ahead of time in case they are needed. Since most matches do already run in a reasonable time frame, (even for seniors!) you shouldn't need a large number of shot clocks and volunteers.
