From my perspective, a cheap one, IF the call from the towers were bad calls (and I've yet to see any video proving they were), then that's unfortunate, but not an injustice unless the rules were not followed.
(In addition to several others depending on angle/site/configuration) IWWF Rule 8.13 d says:
"When boat video is used, the boat video will be monitored on the tower by another Judge who will advise the Chief Judge if he disagrees with the event Judges decision. In which case the Chief Judge and the review Judge will again review the video file to determine which score is correct. If they both agree on a score, that will be the given score. If they disagree or agree that the video does not clearly overrule the score given by the Judges, then that score will stand."
It seems apparent that the tower judges (however many there were) (at least enough to overrule BJ per Horton) called 5. Maybe its a bad call (by multiple judges), maybe not. But the video was obviously insufficient to overrule the scored 5. Unfortunate, but it's not like he got called 5 based on the (bad) video, there just wasn't enough evidence to change it to 6, it would appear, if the rule was followed.
Freddie's score didn't just affect Freddie, it affected the rest of the field, particularly JT. Again, call me naive but I trust that the judges tried to do their best to make an accurate call. And yes I realize JT is obviously a Nautique skier but I still trust that panel of judges to call it as they see it.
I have no opinion on whether Freddie should or shouldn't be allowed to ski this year, but I'd like to have seen him.
