Well, race to 4 would be the way to go.
It GUARANTEES both players 2 breaks at the table each, minimum.
As it stands right now, guy who wins the flip, or the lag, has an advantage, in one pocket terms.
It could go 3-0 with one player breaking one time with the current format.
Think about it.
Guy breaks great, and holds his serve, you mis-hit the break, and sell out an easy counter break and are on defense from there and end up losing.
Guy nails the break and sticks it to you.
If it was race to 4, the player would get the opportunity to adjust, and break again.
A 1-Pkt. race to 4 can, obviously, go 7 games, whereas a race to 3 is 5 games at most. Two more games in 1-Pkt. can be a lot longer. Time is a concern to get the event finished in a reasonable time. Let's look at some numbers from the matches streamed on Accu-Stats.
2016
• 9-Ball -- 15 matches, average elapsed time 65 min., range 32-84 minutes
• 1-Pkt. -- 11 matches, average elapsed time 79 minutes, range 42-130 minutes
2015
• 9-Ball -- 11 matches, average elapsed time 72 minutes, range 46-102 minutes
• 1-Pkt. -- 12 matches, average elapsed time 74 minutes, range 28-approx. 157 minutes
So the average match length has been fairly similar in 9-Ball (races to 9, not 7) and 1-Pkt. (races to 3). But the variability in match lengths is much greater in 1-Pkt. Two streamed 1-Pkt. matches this year and 3 last year went over 2 hours. What if 2 or 3 more games had been added to those matches and played at the same pace? Do the players want the rounds to be delayed even more than they are now by extremely long matches? Do they want to add days to the event? Do the ppv viewers want to watch 4-hour 1-Pkt. matches delaying or eliminating other planned matches?
As for your point about the great advantage to winning the flip or lag with a race to 3 in 1-Pkt., let's look at some more numbers.
I have watched 72 streamed 1-Pkt. matches over the course of the last 6 DCC events and the 2 Southern Classic events. These were all races to 3. In those 72 matches, the breaker won 165 of the 295 games, or 56%. So, yes, the breaker has had an advantage, but perhaps not as great as you thought. And the variability is large. In this latest DCC event, the breaker won 20 of the 49 streamed games, or just 41%.
So, yes, today's 1-Pkt. format can certainly lead to some frustrating losses. But I think that is true in all the disciplines. If 1-Pkt. continues to be played with today's rules, I think the greater good at DCC is to stick with races to 3.
Actually, I, too, would like to see longer races in 1-Pkt., but only if the rules were changed to eliminate the games that go on and on. I'd not only have a shot clock, but a game clock. When the game clock expires, the guy ahead wins the game. That would create some interesting tactics and shot-making as the clock winds down. Yeah, I know -- that would be anathema to the 1-Pkt. purist.
