Some people's impression of the "shootout" match approach was solidified based on an earlier inferior incarnation of the approach, when a shootout occurred simply when players split the first two races to 4. That's too many shootouts.
Now you need to split two races to 4 AND get to hill-hill on the third one. That's like two runners leaning for the tape after a long run and you can't quite tell who is ahead. Importantly the shootout is conditioned on two competitors leaning into the tape.
At this point it is a feature, not a bug, to have the match decision based on something that is in both players control from there. There is a true back and forth--no luck of who came up dry or made a ball and got hooked or had a cueball kicked in or had an open table on a single game.
The best-of-3 races to four match is as discriminatory as between a straight race to 8 and 9, but closer to 9.
