In tennis there is a computer program called hawkeye that uses an elaborate system of cameras and physics calculations to determine the exact location of the ball. It is a back up to the line callers.
Even though it might be a bit expensive, figure skating could use a similar program to determine the exact rotation of a jump. A technical specialist just tell the computer which jump and it will tell if it was 2.789 revolutions or 3.0165 revolutions.
I don't know if such a program exactly be better for figure skating. What if it turns out the most women triples are under 3.0? Or what if it turns out that most men get the full revolutions? Will they set the bar of underotations higher for men and lower for women? Will they try to throw in extra points for complete revolutions, will they try to take off points for slight over rotations? How will effect the fans? Will take something away?
