I have a nice TB mare that I have just switched over to Foxhunting, she did well in racing and I figured she would do well in FoxHunting as well. When I trained her up and ran a trial on her it keeps coming back as a negative 9.24. I've never had a horse come back with a negative number before. Can anyone see what I did wrong with her?
