# Thread: Free Dance JGP Courchevel 2012

1. Edited to add: Hmm. If you like conspiracy theories -- who doesn't? -- note that France's closest cronies are Russia and Canada. Who pulls the strings in the ISU inner sanctum?

(Calculation for France is off a bit because there is a mistake in the original data which I didn’t notice until I was almost done. There may be other mistakes in arithmetic in this hurried hand calculation.)

As SkateFiguring mentions, France is the most independent. USA, CAN, and ITA are tight, as are UKR, BLR, and RUS.
I noticed the obvious mistake and have corrected it. First I noticed the French judge's PCS ranking is the closest to the eventual result, with my error of having two 7's and no 9 standing out. But the observation is still valid. So maybe the French is actually the most neutral or moderate, ending up being the centre of two sides and balancing them.

I did a quick eyeball pair comparison before and appreciate that you have done the actual calculation.

3. I can't stop watching the videos of Cizeron, he is a rock star

4. Yes he is! I foresee a bright future for this couple.
