- Timing. But for a change I was too early as opposed to too late especially when the further end of the curved tunnel was the correct entrance.
- Using a directional without an obstacle name or instead of an obstacle name.
- Failure to keep an indirect eye on Belle as I'm sprinting ahead of her.
On the third exercise, I chose to try the opening two different ways. The first time, I lead out and indicated we were going to the tunnel a la Mecklenburg. The second time, I started with Belle. When I did the lead out, I felt like an eternity passed before I was free to move again, and I thought for sure that running with Belle from the start line was probably the better way to handle this opening. I was somewhat surprised when I did the slow-motion comparison for the video.
