Here's a breakdown of the scoring....
Adelina had a 5 point edge in base value in the LP, Yuna a couple points in the SP. Questionable levels were given on the step sequences, which brought Adelina's overall base value advantage back to ~5 points.
The rigging starts in GOE ... look at the +2 and +3 across the board for Adelina...more towards +1 and +2 side for Yuna on a lot of elements. Adelina is a better spinner, but Yuna is a better jumper. Adelina gets awesome height, but not the same ice coverage, flow, and air position as Yuna. GOE riggage allowed Adelina to overcome her step-out and still maintain ~5 point lead. Without the shady GOE and step levels, Yuna and Sotnikova would have had a similar TES score over the whole competition.
Then you look at the components. Adelina consistently scored in the low 60s. Then once she won the Russian national championship, she went up to high 60s at Euros and almost 75 at Olympics. Just those two points after winning the Russian title and clinching her Olympic ticket, and her score went up 10-15 points almost overnight. The components scores should be much in favor of Yuna, but instead they were basically tied ... only 0.09 difference.
Anyone who says "Adelina 7 triples, Yuna 6, Adelina wins" is being disingenuous.
