It would be interesting to learn how Fargo rating affects the value of having the break. I would expect that value to increase as Fargo rating increases, but I might be surprised.
For someone who doesn't play defense (playing 8-ball, I am assuming), that one guy wins a lot. Growing up playing 8-ball, the first strategy I learned was that it was a whole lot easier to make my balls if my older brother made some/most of his balls before I came to the table. That's one old school hustle I would have never fallen for.

Note: This tracks breaker's win % by their own Fargo rating, not
by rating gap. Win % climbs with rating mainly because higher-rated
players win more overall — not necessarily because breaking itself
matters more at higher levels. When restricted to closely-matched
opponents (within 50-60 Fargo points), breaker win % flattens to
~49-51% regardless of rating band.
