The way the riders and minders wrecked section 2 shows why the minders should not be in sections. Observers had to leave their meeting to basically go and protect the work that had been put into the sections. Boulders were lifted and rolled into place by riders and minders, they basically wrecked the section. Would people like to watch every rider get through a section that has been made easier by minders and riders or would they like to see the riders use the skills they have to tackle a challenging section.
"Everyone is an observer" at these events and no observer can see all areas of the sections, though they do their utmost to. If people are so observant they will be putting their names down for the next world round to demonstrate these skills?? Get off the soap box and stop knocking people who are giving their time and effort only to be knocked by these "observant watchers". Even at club level dabs get missed, and it is no different even at this level. If there was even the slightest doubt about a dab then the observers were instructed to give the benefit of that doubt to the rider.
Minders and riders have to be watched so closely as they try to move rocks in the sections, even when the trial is running. You have to watch them like a hawk to stop them. The top riders are the worst as as soon as your attention is on the rider coming through the section they and their minders cross the section, dragging rocks into place or moving obstructions out of the way.
Minders should not be in the section at all unless they are needed to catch - they know the rules but constantly had to be asked to leave the sections, running up the section behind a rider was not allowed and both the rider, minder and team manager know this.
