I'm probably in the minority here, but I never understood the 6.0 system. Yes 6.0 was a perfect score, but where did the deductions come in? How could a skater complete all the difficult jumps cleanly and still only score 5.6? How was it not perfect if it included all 6 triples, good spins and footwork? How can you get 5.9 if you fall? Wasn't that suposed to be a .2 or .3 deduction? The new system makes much more sense to me. The value of what the skater does on the ice is added together for the final score. There are no deductions from a fixed total, which dosn't make sense to have because not all programs have the same content or difficulty. I was always confused with the 6.0 system except on the rare occation. Under the CoP at least I can find some justification for the marks and work out where the deductions came from.
The CoP needs work and the judges need to be known, but I still will take it over the 6.0 anyday.
