The following is very rough as the on-screen clock at the SL site doesn't do decimal points and I've only measured from the first hurdle (H1) but it might give an indication of how each race unfolded.

The front runners in both races were still well there at the last, suggesting neither race went over-fast and clearly the novice race was much more slowly run so we should expect the leaders not to fade.
However, the pace setters in the big race didn't fade either as Highly Prized was bang there when brought down at the last. I think JJON Jr deserves credit for getting the fractions close to spot on but I don't have enough accurate detail to quantify things beyond the above.
Chantry House has certainly sped up the run-in. I imagine he'll get a big sectional mark-up from the likes of Simon Rowlands.
The Betfair has clearly started much faster and kept the pace up more persistently through the race with the novice race, as I suspected, closing down all the way up the straight but still a long way behind at the line.
