Actually, her 3Z(e)+3T< would still get a BV of 8.9 points (instead of 10.1), and GOE would be -1 to -2 with the flutz, since it was executed well with preceding steps and good height and speed. With the GOE deduction, it would have scored about 8 points, I'd imagine, instead of 11.1 that she got.
And then with the sequences being level 3, she would have lost 1.2 points in BV, which is about 1.4 points with GOE consideration (since GOE bonus on 3.3 versus 3.6 BV is negligible.
That's about 5 points less.
Also, Sotnikova had 69.60 PCS at Europeans (so she had certainly been above 63.99 -- both hers, Gold's and Julia's PCS shot up from the beginning of the season). I still think 74 points was way too high, but above 70 PCS for Sotnikova I could picture being justified (Lip should have been below 70), with Mao's PCS a point or two higher than hers. I also thought she didn't deserve more than 33 PCS in the SP (again, getting PCS on par with Kim was ridiculous, even if Sotnikova did have her best SP ever).
So with her PCS dropping 2 points in the SP, and 4 points in the LP, and with the deductions on her 3-3 and her step sequence, she would have lost about 11 points, ending up with a final score of 213, which would have been enough for bronze. 210-211 if we reduce her GOE, which was pretty high on certain elements. I would have then swapped Kim and Kostner's PCS, giving Kostner the win. Saying she deserved bronze is totally legit, but saying she deserved 20 points less is too extreme... at the very worst, Sotnikova should have scored 13-14 points less than she did.
