Given that Sasha fell twice, a 9 point lead in the LP was not that great. She would have more than made good the difference had she skated clean.
Given that the program Shizuka doubled a planned triple and landed the same # of clean triples as Sasha (5) losing by 8-9 points is not that great. Given that Shizuka's performance was worth 10-15 points less than her regular practice performances in Turin, losing by 9 points with 2 falls is not that great.
If Sasha had skated clean..... Well one could say if Shizuka and Slutskaya had skated their best Sasha wouldnt have had a hope of winning anyway, which would be true. Yeah Sasha skating clean which she has never done in her life anyway, and combined with all of Shizuka doing a very simple program with a major mistake herself, Slutskaya skating horribly, and Kwan and Asada both out of the Olympics, could have won with all those events somehow combining. Somehow I dont see much meaning in that.
I agree that Shizuka had the superior jumping technique - there is no question about that given that Sasha seemed incapable of ever putting together two clean programs in one competition.
She isnt capable of it as you admit yourself, so what does it matter. Shizuka was in fact more likely to have skated much better than she did than Sasha. Shizuka's practice performances in Turin or her 2004 Worlds performance (coupled with now having a "name" unlike her undermarked 2004 Worlds LP) would have beaten a fantasy never seen before clean Sasha probably by an even bigger margin than she actually won by.
However, Sasha's spins, spirals, etc and all round general grace and artistry were far superior to those of Shizuka.
Which is why Sasha was outscored in all those categories in the long program in Turin. Shizuka's basic skating quality is far superior to Sasha as far as edges, flow, speed, power, ice coverage too, in addition to her jumping. Even if all you said were true Shizuka has no real weakness in her skating to the extent of Sasha's jumping and her basic skating. She is very strong in all of jumps, spins, footwork, spirals, musicality, choreography, stroking, which a couple of those Sasha is only mediocre in, regardless how great she is at some of them.
Hence, had Sasha had a better jumping technique and temperament, and had she been able to skate clean throughout a competition, in my opinion she could have been a triple world champion (2004,05, and 06) and Olympic champion (06).
Sasha was never winning the 2005 Worlds. Irina was on her home ice, was dominant that year was skating the best she had ever had going into Worlds, and had all the momentum. Sasha skated the closest to a clean competition she ever has done, and Irina botched 2 elements in her short program and had a triple jump discounted in the long and still won by a big 2 fall or so margin. She would have even had a better chance of winning the 2003 Worlds than 2005 (not that I think she could have won the 2003 Worlds either).
2004 Worlds she would have won had she skated better but only due to Shizuka's lack of name at the time and all of Kwan's problems at those Worlds.
2006 Worlds was a gimme since the field was a joke but she still blew it.
Basically, the avoidable (with better technique and temperament) falls and mistakes she made in each of those competitions cost her every one of those titles.
Maybe the fact she doesnt have better technique just means she is not super talented in all areas needed to be a champion. She might have alot of talent for spins, spirals, pretty positions, and other things but not much talent for jumping or basic skating ability.
