Whether you argue that Gold was over-scored by the US judges at Nationals, the US judges were right in line with international judges when it came to comparing similar programs:
Skate Canada SP: 3T/3F< with "e", 2A with -3 GOE across the board, fall, a L1 combo spin.
Base TES: 29.03. Actual TES: 27.53. Avg. PCS: 6.42US Nationals FS: 3T/3F<, 1A, fall, L4 combo spin.
Base TES: 27.70. Actual TES : 28.74. Avg. PCS: 6.46.
Just about identical scoring between US and international judges for similar performances.
Rostelecom Cup FS: edge calls on both 3F's with -GOE on both, -GOE on doubled the Lo and Lz and singled the Lo in three -jump combo, -GOE on the 2Lo, but L4 spins, L3 steps, the better of her GP FS,
Base TES: 50.18. Actual TES: 54.77. Avg PCS: 7.26.US Nationals FS: Landed the 3Lo and 3Lz instead of doubling, replaced solo 3F with 3S, did 3/2/2 and 2A/3T with lots of GOE.
Base TES: 60.31. Actual TES: 70.11. Avg PCS 7.67.
For the elements she had in common in both the RC and US Nationals, here are the comparisons:
RC 11.5 (+1.4 GOE, 1-1, 1-3, 7-2's).
USN: 11.9 (+1.8 GOE, 4-2's, 5-3's)
RC: 4.09 (+.79 GOE)
USN: 3.8 (+.5 GOE)
L4 Layback Spin:
RC: 3.7 (+1 GOE)
USN: 3.49 (+.79 GOE)
L4 Flying Combo Spin:
RC: 3.79 (+.79 GOE)
USN: 3.71 (+.71 GOE)
L1 CH Sequence
RC: 2.6 (+.6 GOE)
USN: 2.7 (+.7 GOE)
L4 Change Foot Combo Spin
RC: 4.43 (+.93 GOE)
USN: 4.43 (+93 GOE)
For the five elements that both FS's had in common, there is a marginal difference in scoring. In fact, the international judges gave Gold a slight .08 margin.
There was one element called higher at USN:
RC: L3, 3.8 (+.5 GOE), 8-1's, 1-2.
USN: L4, 4.8 (+.9 GOE), 6-1's, 3-2's.
Between the level upgrade and increase in GOE, she gained an extra point from the US judges.
The substantial difference in score between the RC and USN FS was technical, i.e., the five jump elements that were not in common to both programs. Just doing the math on the downgrades jumps, Gold lost 8.63 in base right there. In RC, she had -GOE on three of the five, and three of the five were unintentional downgrades, with the 2Lo being both. That's a lot of points left on the table, as well as a negative against the overall quality of the program's jumps. At USN, she landed all five beautifully, although the US tech panel and judges might very well have missed the edge call on the solo 3F combo, for which she got .1 GOE.
Still, at RC, she did receive a 9% bump over base TES, while at USN, she received a 16% bump over base TES, for a program that was 20% harder, and 95% of the increase in difficulty was due to the increased jump value. For a substantially better executed and more difficult program -- I don't hear anyone arguing that Gold was Mao Asada or Carolina Kostner at RC -- she received a bump of, on average, .4 per PCS, or 3.25 additional PCS in total, after the 1.6 factor for the Ladies' FS.
To recap, at worst the US technical panel may have over-leveled Gold's step sequence by .5 and missed an edge call on a 3F, and the US judges may have been a little overenthusiastic about the five jumps elements that weren't in common, and for which we have no international panel scores to which to compare. About the .4/ea bump in PCS Gold received from the US judges for a superior program, it's half of the PCS bump Wagner got from international judges on average between her GP's last year and her 4C's FS, and twice what Wagner got between her GP's and Worlds, and it's a quibble over very few points in the big picture. If the three points were removed, and the .5 for the step sequence and another point for the edge call, Gold still would have won silver.
As for whether other skaters were robbed, I'll leave that to people who've watched all the programs, but the US judges were firmly in the corridor with the international judges when scoring Gold, and the technical panel was fairly close with their international peers.
