Just looking at the sectionals tonight, the final 2f of the Pouliches was run in 22.19 seconds - or 111.9% of the overall pace - which suggests that they went an utterly farcical gallop with the form looking relatively suspect.
The final 2f of the Poulains was run in 23.52 - or 102.2% of the overall pace - which suggests they went a far more serious gallop. It's hard to draw any conclusions without standards or anything to compare those sectionals with, but my initial impression would be that the sectionals indicate that they went a decent though probably not overly strong gallop.
Of course this doesn't take into account the energy the Fahey horse expended in getting to the front or indeed the fact that he seemed pretty free even on the lead.
