Watched the race. Not sure of the logic of how reflects badly on Bryony. But fair enough.
I don't see the horse jumping sharply left or violently left in the race above. Not at stratford either. It might have done in other races. I wouldn't want to get bogged down in terminology. (Note that all this is absolving Dunne of stupidity for going up it's inner. Had the horse a reputation for jumping violently left, going up it's inner would have been spectacularly stupid).
I think you are right, that the horse does corrects himself by edging left when jumping, and he did actually interfere with Agentleman at the third last in the above race doing just that. However I would class it as a racing accident - ten a penny -not as violent as Lee Edwards incident. And Agentleman was a length closer than Robbie Dunne's (cillians well) fatal fall meaning he was actually crossed. (Unlike Bryony in the Cillians Well incident). The point is the Bryony allowed the horse to edge left when jumping when it want interfering with others.
Did Kielan Woods deserve to be subjected to abuse, bullying by the jockeys following the race? I could see how that end up in a physical fight. Does this count as evidence of Kielan Woods being a dangerous jockey?
How far ahead of Robbie Dunne did Bryony need to be for it not to judged dangerous? It's clearly far greater distance for Bryony.
