Well, I don't want to be off-topic, but I don't think that you have your case here. To prove what you are claiming, Yuna should have won FS at 2010 worlds by TES even with her errors, but that was not the case. Yeah, Yuna fell on 3S - the weakest triple planned - in 2010 worlds but Mao got UR and negative GOE for her 3A+2T as well. Their BV difference was pretty much negligible because of this - Mao had 2.25 points more - and then including GOE, Mao still got more TES. The difference became bit smaller within 1 points as Yuna got all of her money jumps - two 3Lz including combination, 2A+3T - and got very good GOE there, rightfully so.
However, even if you rescale GOE and give smaller GOEs for both skaters, these results would not change. Yuna won FS there not because of GOE, but because of PCS. Her PCS edge over Mao was bigger than the difference between their BV. Whatever scale you may apply to GOE in that competition, Yuna would win the FS. If you do not agree with the call on Mao's 3A or on their PCS, this is really different story which has nothing to do with GOE scales. This result did not change the overall result anyways, and I can hardly see it as the system's fault regarding GOE scale.
GOE scale got changed after Vancouver pretty much because of Yuna's gigantic scores from 2010 Olympics. Now that Hanyu is getting crazy scores, I am pretty sure that there would be on-going discussion with the scoring system as well.
Back to the topic : My favorite ladies competition was 2010, and then 1998. There were exciting rivalries, great performances, dramas, etc. Performance-wise, 2014 comes close too, but judging controversy was way too much to bear. However, I must note that I still frequently watch Yuna, Caro, Mao's FS at 2014 (SP from Yuna as well).. I was very happy to see Mao finally skating within her full potential there (FS). I hope she can pull it off again!!!
