I took three dogs to practice yesterday- Koira, Pallo, and Chester, who is a corgi on our flyball team, but staying with us for the holidays. All the dogs ran really great. I got a chance to have team mates record Koira's turns, and I think we may have *fingers crossed* figured out a set up that keeps her high on the box, no double hitting, no bobbling, and nice and snappy.
In addition to the prop changes noted in the video between the clips, I also started calling Koira earlier, when she hit the box instead of when she got the ball, to encourage her to push off faster back to me. I did this change about the same time we put in the extra height in the box jump, so the improvement could be due to either, but I am thinking both.
