Test Plan Example Dressage Test Movement- Half Circle Returning To Track?

Dressage test movement- half circle returning to track? - test plan example

I am planning my tests for a show to come and have a quick question: In tst 1st Level 1, for example, there are 10 million by ex-circle to the title in the H.

One of my professors said, traveling in the middle circle of X, but keep the curve h. Another said that a half-circle X, and then make a straight line to H. Both coaches are drivers at level 4, but Haven 1. Class in a number of years.

What should I do? (Use this when 6-9s in it, if you are 5 or below)

Thank you in advance.
