Besides Yuna and Mao, the Russians are the only other women competing in Sochi who have surpassed a total score of 200. Adelina achieved this despite doing only 4 clean triples in her LP, and Julia having multiple "e" calls on her lutz jumps. If they manage to go clean, how high can they score, given that they will have home crowd support?
I can see Julia and Adelina hitting 73 - 75 at home in the SP if they hit their jumps clean and get full levels on their spins and footwork. In the LP, I don't think they could get up to 150 (Yuna's peak potential) but they both plan one more triple than Yuna and score better on the spins, so I think mid-140s is possible if they hit everything perfectly. The fact that Julia and Adelina scored so closely to Carolina on PCS makes me think Yuna isn't going to have a huge advantage against the Russians at home, maybe 2 points in the short and 3-4 in the long.
