My question is who gets to set the pacemaker time and why can't there be 2 ?
Emma is the only one that uses them.

"...come the spring Krummenacker will be back pacing 800s, 1500s, and miles here and abroad, earning six figures if he can rabbit a half dozen races indoors and a dozen or so outdoors. "
"Krummenacker's rabbiting career began in the outdoor season of 2009 when his agent, Mark Wetmore, called to ask if he wanted a two-event pacing assignment at the Aviva London Grand Prix race in July—the 800 and one-mile."
"Shinkins, like most rabbits, didn't sign a formal contract for Millrose; her fee came about via a simple verbal exchange between Jordan and her agent, Paul Doyle, who is her husband. (Scherer's agent made his agreement with Jordan over e-mail.) There have been reports that rabbits don't get paid if they miss their marks, but that doesn't seem to be the case. What rabbits do know is that if they consistently mistime their laps, they won't be rabbiting anymore. Shinkins looked almost offended when asked if she had any thoughts about not hitting her mark, about 33 seconds for each of her four 200s."
"RACE DIRECTORS AND COMPETITORS LOVE experienced rabbits like Krummenacker and Shinkins because they can count on a consistency of performance. But with late scratches, injuries, and a scarcity of qualified pacemakers, finding a rabbit for a race sometimes becomes a last-minute scramble."
"By the time the rabbit toes the line, he has his specific instructions on what pace he is supposed to run over the first half of the race. Those instructions were communicated to him (directly or through his coach or agent) by the meet director, who has himself consulted with the race favorite, or favorites. At Millrose, it was eight-time winner Lagat who decided the pace.
But occasionally the rabbit discovers that he's a pawn in a chess game going on among the top competitors, which on at least one occasion happened to Krummenacker at the starting line."
"But the most difficult thing for a rabbit is deciding what to do if the pack doesn't go with him—a common occurrence."
