Thank you everyone.
I decided to draw up the pictures in Paint to discuss the Pattern #1 scenario further.
The pattern called for:
1) Walk from cone A to cone B
2) Pivot 360 degrees at cone B
3) Trot from cone B to cone C (judge is standing at cone C)
4) Set up for inspection
5) Pivot 90 degrees and trot away to line up.
Hmm, there's supposed to be a back up in there, but I can't quite remember where it was. I may also have gotten my trots and walks backwards, but that shouldn't effect the concept of what we are trying to discuss.
So is the general consensus to stop at the cones when your horse's front feet lined up to the cone?
So you would have your horse's front feet lined up with Cone A. Then you would walk to Cone B and stop with your horse's front feet lined up with Cone B? Do your pivot and then stop at Cone C with your horse's front feet lined up with it?
Yes, of course you want to leave enough room between your horse and the cone so that when you make your pivot, you don't run over the cone.
I think we seem to be in agreement for Pattern #2. I'll post it anyway for visualization.
1) Walk from Cone A to Cone B.
2) Pivot 90 degrees.
3) Trot from Cone B to Cone C (where the judge is located)
4) Set up for the judge.
5) Pivot 270 degrees.
6) Trot to line up.
Apparently the backing up must not be important to me because I can't quite remember where it was in this pattern either!! Haha.
Makes sense to stop at Cone B with your horse's hind legs lined up with the cone, so that when you do your 90 degree pivot, you are aimed right for Cone C and you can trot straight toward it.
If there any preference on how close you should stop in front of Cone C? Just a few feet?
