From a Bloodhorse article last year about the new gate:

"The horse breaking from the inside post will break farther away from the rail this year, as will the horse on the far outside relative to the outer rail, Jordan said. This is due to the length of the gate being shorter than the two other gates combined while also considering the gap between the two.

The interior of the stalls are an inch and a half wider than the track's usual gate, Jordan said, though the dividers between the stalls are narrower.

"So rather than coming out like from the 1 (post), where it used to be, you're almost coming out of the 3 path," he said. "So instead of coming out of the 20, the way it used to be, you're almost down to like the 18 or the 17."
