When you race you horse upside down, the slowest quarter will generally be the last one! If they believe that it cannot better 29 for the last quarter, they are obviously trying to gas the other horses chasing, or hope they have to big a lead to be caught!
I don't agree with the horse can't run a last quester quicker than 29, if you go slow enough, a snail can run home in 28! If you can run a quarter in 25. 7 out of the gate, given a sit in a "normally" run race, I think you would run quicker than 29 on Menangle. Give it a "cuddle" run and we will see!
The horse must be a speedy 1200 metre horse, keep it in mind for the Flying K series!
It reminds me of some of my old favourite horses from the standing start days!........Captain Gay & Tiny Rebel!
