I watched the horse all the way around because I had a "play" on him. This is not exactly to your point but the horse was not as wide going around the turn as he was in the stretch. It looked like Richie took him wider as they were entering the stretch, whether it was to find good ground or just looking for room to let him go. It certainly took him awhile to pick the others up once he got into the stretch, so maybe he did find better ground at some point.

From previous posts, I believe TG takes into account where the horse is at 3 or 4 points around the turn and not just where they are when they enter the stretch.

Those 3 noses on the wire finishes are fun at 15-1.
