Anyway more to the point her very weak, shallow, and shaky edges were a large part of the reason for her inconsistent and rather mediocre jumping which detracted from her otherwise beautiful skating. After all takeoffs and landing edges are the main basis of a successful jump, if your edges are poor your jumping likely wont be great either, and that was true of Sasha. Had she improved her edges in general, and had stronger takeoff and landing edges, her overall technique would improve, and her jumps would become more repeatedly landed cleanly as well. This in addition to the greater speed and overall basic skating quality of her stroking and general ice coverage, had her edging been stronger, even if the judges were quite generous and never hit her in skating skills in the scores anywhere near as they should have. Still despite her perfect positions, elegance, and later in her career great choreography and musicality (not so much before 2003) she regularly got lower presentation marks than Michelle Kwan, and often even lower presentation and PCS than the ugly positioned and mostly unartistic Slutskaya. Obvious reason for that had to be her inferior speed, ice coverage, edges, all things associated with her basic skating and edge quality, so while the biggest thing was her jump problems were largely related to her poor edging, her 2nd marks would also have been even higher if it was stronger. Contrary to what you suggest, Sasha's history shows she cant win anything if she makes mistakes, not even her own Nationals when Michelle Kwan or Sarah Hughes were around, not that it is the other skaters who have to make no mistakes to beat her. Perhaps improved edges would not only have helped her skate more clean programs with all clean jumps, but further improved her 2nd mark to give her the mistake buffer she was never good enough to have.
