Today, figures would be more verifiable and less subjective, given that cameras are so good these days that they can take a picture of the ocean from space and see a swimmer in the ocean (check out Google Earth). You could show how close the patterns were. There is software used in modelling that could measure the diameters of the circles, check whether 3 turns etc were at the correct position in the circle, etc, verify the rounds, check whether circle had the same diameters, etc. The entire technical grade could be completely done by software, with only a PCS grade for flow & body position & such done by subjective judges. Heck Speedy & Rogge would Love it.
