Re: Yu-Na news
Mao also has problems with URs though, and last I heard she still doesn't have a true lutz. Further, as we've seen in men's competition, the men who do 4t-3t as their combination in the SP which is worth about 4+ points more than the men who do 3lz-3t or 3f-3t, don't seem to really have that big of an advantage in points. If the skater who does the 3-3 is good enough, he'll get the same score if not higher than the skater who does the 4-3, and this is assuming they all are clean (Worlds 2010 as an example). So the same thing might happen with the 3a, even though it's worth 5 more points than a 2a, it's likely Yuna will be able to make up for those 5 points and potentially more, elsewhere in her program.
There are several things wrong with your argument:
1.) GOE values have been decreased for jumps that aren't the Triple Axel or Quad. Yu-Na is no longer going to get as many extra points for her jumps (nor will a skater like Patrick Chan with his 3F-3T combination in comparison to a 4T-3T combination from Joubert).
2.) Patrick Chan got more points for his spins and footwork than Joubert did at 2010 Worlds. This is NOT the case with Yu-Na. Mao gains just as many points as Yu-Na in this area.
If you compare Yu-Na's jump layout to what I predict Mao's new SP jump layout will likely be, along with probable GOE values, Yu-Na is several points behind and can only make up for it in the PCS (and she'll only be ahead of Mao by 1 point at most there if they both skate clean).
Mao:
3Axel (+1 GOE) ---> 9.5 points
3Flip-3Toe (+1 GOE) ---> 10.1 points
3Loop (+1 GOE) ---> 5.8 points
Total -
25.4
Yu-Na:
3Lutz-3Toe (+2 GOE) ---> 11.5 points
3Flip (+1 GOE) ---> 6.0 points
2Axel (+2 GOE) ---> 4.7 points
Total -
22.2
If Mao's 3Axel gets downgraded, then they are pretty much equal. Mao usually only gets downgraded on her 3Axel when she is focusing on doing it in combination, though.
Mao's LP will similarly be worth more points and Yu-Na is at an additional disadvantage because she is not allowed to do 3 Double Axels in the LP anymore. She's has to put the 3Loop in the LP, which will hurt her consistency, or she needs to take the 2Axel-3Toe combination out of her program, which will lower her points in comparison to Mao even further.
