Ashley's base value was 27.20 which was lower than all the skaters in the top 10 except Carolina and Akiko. Besides the lower value on jumps (obviously a 3f-3t combo is worth a lot more than a 3loop-2t combo) she also go a level 3 spin (she generally gets level 4 on all of them). Regarding 3T-3T. The base value of 3T-3T is 8.2 versus 6.4 for a 3Loop-2T.
Carolina and Akiko did their elements well enough that they got more +GOE (4.46 for Carolina, 3.77 for Akiko compared to 1.60 for Ashley). Elene G. had a similar base value 27.6 with that single axel, which cost her a lot of points, but she did well enough on the rest of the elements to get stronger +GOE as well (3.26 points).
Ksenia did not get marked for URs in the SP and had mostly +GOE, though not as high as the otherd. She had the fourth highest base value of the night at 29.10 only getting passed by Kexin Zhang of China (29.70; she beat Ashley in TES, but lost to her in PCS), Alena and Kanako (both had 29.90)
As for Mao, while the downgraded 3A hurt her for sure, she scored level 4 on all her elements, which probably added some points to make up the difference. Her 3F-2Loop is a decent scoring combination, only 1.1 points behind a 3T-3T. Her base value was 28.6, which was only beat by the four people I mentioned above. Add solid +PCS and you got the reason why she beat Ashley.
