Should there not be a rule that stipulates that in a rankings tournament, the boat camera needs to be HD (min. 720p) and record at (lets say) 120fps? That way it should be easier to tell if a skier did or didn't go round a buoy, when reviewing frame by frame? I'd say the same goes for the gate cameras too. The reason I say this is because there have been instances where the quality of the freeze frames haven't been that great and therefore makes the final decision subjective.
