Yes, maths is clear.
If she landed the 4S clean she would NOT regain +9.7, as she already got that BV for quad. She would have got +4.85+ 1. Also that's not how GOE works, shed get less than a point for +1. I'll use your maths anyway and subtract 4.85 from it, and shed be under Alena...
This reminds me of the beginning of last season with people repeatedly insisting and claiming to do the math
multiple times to prove that 3As won’t have much of a mathematical advantage against quads. The math was incorrectly done
multiple times.
A fall on a rotated quad is half the value of that quad, not zero. Getting +3 GOES across the board is also not equal to 3 points.
Yub Lub’s Tutorial on Calculating GOE
1. There are nine judges at major international competitions.
2. Nine judges gave the following for a hypothetical 4S (0 1 2 3 4 5 0 1 2)
3. The highest and lowest numbers are dropped. (1 2 3 4 0 1 2)
4. The numbers are added together. (1+2+3+4+0+1+2=13)
5. The total is divided by 7 - the number of judges. (13/7=1.86)
6. The total is then multiplied by 10% of the value of the 4S. (1.86 x 0.97)= 1.80
7. The GOES is 1.80. This skater scored 11.5 for the 4S. 12.47 if 4S was in the second half.
Note: For combinations, the GOE multiplier is based on the jump with the highest BV, not the first jump in the combination. It just so happens that the first jump is usually the most valuable, but that’s not always the case. Example: Medvedeva’s 3S+3Lo. In this case, the GOE multiplier is based on the 3Lo, not the 3S.
