OK... at 0:07
you pinched the flank. You gave him the look of the clockwise Go Around, and he took it.
Instead of just turning late like that, step forward, towards him a bit, and he'll stay out front. Be careful of pinching the flank like that. It's a great way for a pattern trained dog to wind up on the wrong track in flatwork.
The recovery at 0:11
was the orientation and pressure point mentioned above. Because you were facing him and you grabbed him and pulled him to the right is exactly what was missing when you pinched the flank above.
Deck is biased to the clock direction. He likes to run clock. That makes your pinched flank even more dangerous because he is dialed in to seeing that directional cue.
Be sure to vary the pattern. You are really running the traditional PVR pattern. That pattern, given the reward placement out in front of the handler, will reinforce a tighter flank on the round end of the pattern. If you throw out to the flanks and pull between 90 and 120 degrees you can get a much looser, flowing flank.
Good work! Deck's a stud!
