Yes I agree with the others that your horse is anticipating and not really waiting for the cue. Not something to encourage. Like the others said, change things up.
T will respond to the slightest cue from me, but if she is anticipating before I cue, than I stop her and transition back down and start over. She knows not to get ahead of me. Though it does feel like she reads my mind, she is just very intuned to my body language and is responding to the slightest change.
Haven't reached this level of communication with Walka yet, but will be very clear with him too about not getting ahead of my lead.
Be the kind of woman that when your feet hit the floor each morning the devil says, "Oh crap, she's up!".
