Show prep dressage lesson with John

Today we practiced Test A in the proper size arena.  John had a handful (exactly the number I could handle) of really great suggestions for improvement:
First - wait to turn left until "G" (between H & M) - I have been starting to think about it closer to X.
Second - use some inside leg (almost a bit of leg yield) on the 15 meter circles to keep them from being square.
Third - to get the deep corner, which comes out into the lengthened trot, warm up with bent to the outside on the corner, bend inside on the short edge, bend outside on the corner.  Do this a few times, then just hint at bend to the outside while keeping the inside bend.  After a few times of this, Charlie could go deep in the corner and it gave me so much extra space to come out of it and start lengthening.
Fourth - it isn't a "progressive lengthening", just lengthen.  So once I have it, don't keep stretching it out, otherwise I haven't done the movement.
Fifth - at the end of the stretchy trot circle, leg yield a couple of steps back to the short side before coming back to trot to walk.  Otherwise, the combination of lengthen, stretch, trot, walk, free walk makes Charlie sluggish - more sluggish - most sluggish.
Sixth - use a bit of inside hand to try to keep Charlie from tilting his head so much.
Seventh - in the warm up, do a canter, lengthen, trot, immediately lengthen the trot.  Do this down the long side just before we go in.  It gives Charlie a jazzed up trot to start out.
Eighth - I can either sit or post (yay!  I can sit!) but don't switch half way in a movement.  Definitely post the first trot lengthen.  If Charlie is sluggish, sit the second one.  A few of the movements are kind of obvious, like lengthen the trot, stretchy circle, trot, walk - that is all posting.
John had us do a few more exercises, lengthening the canter to lengthened trot and doing some leg yield at the trot and canter (!).  Charlie actually felt really great to me, and I'd be really happy if he felt that good at the show.
