That decision sounds about right. As I noted on the earlier thread, "tunnel vision" near the end of a course could have prevented her from realizing the severity of the situation, and the FEI seems to agree. She should have pulled up to assess the situation, and she is punished for failing to pull up, but not punished at the level which would be appropriate if she fully realized what was going on.
Ping to the horsey set.
