I think it's certain that they will improve, since it's pretty much impossible for them to get worse than they were here.Purich/Arcieri hopefully improve over the next few weeks.
That was a disaster. I attribute it to first-competition nerves, and I'm sure they're skating much better in practice than what they showed today. Nevertheless, I wonder if it might be wiser of Skate Canada to assign them to JGP competitions which are as late as possible rather than to assign them to Graz. Even though they are both good skaters, they need more mileage together (at least IMO).
