[VVV] Darren took that horse to the top and he simply bottomed out the field...you'll note that each quarter went by progressively slower than the previous 26.4, 28.1, 28.4 & 29.0.
What you saw there was a classic example of speed holding up on the front end on a track that is approaching being lightning fast now...and it was a lesson in how that track should be driven. The US drivers do exactly that day in day out over the mile and nobody give it so much as a second thought. Btw...inferring there was some sort of nefaious behaviour involved by way of a throw away 'recently USA returned trainer'...is not a very charitable thing to do.
