#1 - Kristi did not have better presentation than Tara.
WRONG. Kristi was always considered far stronger in artistry and presentation than Tara. Tara's presentation is the exact reason Tara needed Kwan to make major mistakes to score almost all her big wins, and that people were shocked at the Olympics when Kwan skated cleanly and actually lost to Tara.
#2 - Tara did TWO 3-3 combinations and they were both late in the program (one of them being at the very, very end).
A triple-triple sequence is not a triple-triple combination. A triple toe into triple salchow sequence is much easier than even a triple toe-triple toe combination. It is what people who cant do triple-triple combinations like Maria usually go to. For Tara it was something a little extra but hardly a big deal.
#3 - Kristi did not make minor mistakes, she made major mistakes. She nearly fell on the Loop. That right there would have ensured she lost the Gold to Michelle. The second mistake of doubling the Salchow wasn't AS costly since it was an easier jump, but that too would have ensured she lost to Michelle on its own because then she would have only had 6 Triples vs. 7 for Michelle. And NO judge would be marking Kristi higher on artistry.
Another fail. Kristi beat Michelle in artistic scores when they met at the Ultimate Four in 97 when Kwan was already in her prime and had some of her best programs (people might say they were even better than 98 had she actually skated them cleanly more), an even which Michelle won only after Kristi imploded on her jumps in the 2nd round after leading. Kristi was given a perfect 6.0 and almost all 5.9s for presentation in the short program by ISU judges who were probably biased to the amateurs before Michelle even skated. If Tara managed to tie Kwan in presentation by half the judges in the long program, it is silly to just say with certainty Kwan would easily get higher 2nd marks than Kristi.
#4 - Kristi's marks in 1992 were nearly as high as Michelle's in 1998 because the standard was lower in 1992.
The eventual standard is in hindsight. When Kristi skated left to skate were Ito, Kerrigan, Harding at her peak, and Bonaly. In 98 left to skate were Tara, a fat slumping Irina, past her prime Chen, and Butyrskaya. The potential standard in 98 which could not be known when the first skater of the final flight finished was alot higher in 92. Ito at her best is way better than Tara. Harding at her best was devastating. Kerrigan in her prime was even a much superior skater to what Slutskaya, Chen, and Butyrskaya all were in 98 (not very good, with only Maria one of the weakest World Champs ever in her prime of those three). Kristi still managed exactly the same marks as the 1st skater of the final flight with potentially much stronger skating to come in 92 than 98.
Silly arguments. There's no way of knowing how Michelle would have adapted if she had been healthy and competing in 2006 and 2010. Given how well Michelle skated in 1998, though, you have to assume she would skate that well in 2006 and 2010 under the new rules. In 2006 Shizuka doubled her 3Loop, whereas Michelle did not in 1998. In 2010 Mao was hardly invincible for the Silver - she missed two jumps and Yu-Na beat her by over 20 points. Someone as artistic and renowned as Michelle definitely could have placed above Mao in 2010 without any Triple-Triples (or Triple Axel).
Yu Na would have destroyed any women in Olympic history with her Vancouver skates so the over 20 point margin over 2 programs means nothing. She was also overmarked a bit which exagerrated it more. Mao with 3 triple axels over the 2 programs would have still probably won any other Olympics in history, especialy under COP. Especialy considering Mao is considered a very good all around skater outside of the jumps too, even if people werent crazy of her 2010 programs.
What you are saying on Michelle is purely speculation. People didnt say she was past her prime in 2004 when she did one of her greatest performances ever at Nationals and was favored to win Worlds. She mysteriously became past her prime once COP was interested. Kwan is an excellent skater but her strengths as a skater were more rewarded under 6.0. Note I am not neccessarily one who prefers COP either, in fact I dont, but COP is what we have had since 2004 like it or not.
