Just going by protocols at worlds, the one thing C/P has over Z/K is they didn't get level 2 steps or patterns. Z/K are pretty new still and it shows in the levels for those elements.
Better material will help, but I think they can get some technical advantage over the patterns and steps. (hopefully that will also motivate Z/K to work hard to not get those level 2s. )
I don't think that just the protocols from Worlds are the be-all and end-all.
It's not as if Z/K always get Level 2s -- for example, for 2026 Worlds RD step sequence, Z/K earned the same Level 3s as C/P. And Z/K earned 3.14 GOE versus C/P's 2.69.
And it's not as if C/P always are immune from Level 2s.
Yes, Z/K have room for improvement, but they are not alone here.
At
Olympics:
Z/K and C/P both earned PSt3. GOE for Z/K was 3.35; for C/P was 2.56.
Z/K rhythm: MiStW2+MiStM3 7.83 + 3.29 GOE = 11.12
C/P rhythm: MiStW3+MiStM2 7.83 + 2.99 GOE = 10.82
Z/K free: DiStW2+DiStM3 7.83 + 3.14 GOE = 10.97
C/P free: CiStW3+CiStM2 7.83 + 2.53 GOE 10.36
At
2026 U.S. Nationals:
Z/K earned PSt4 versus C/P's PSt3. Same GOE of 3.35 for both.
Z/K rhythm: MiStW3+MiStM4 8.58 + 3.14 GOE = 11.72
C/P rhythm: MiStW3+MiStM3 8.20 + 3.29 GOE = 11.49
Z/K free: DiStW3+DiStM2 7.83 + 3.14 GOE = 10.97
C/P free: CiStW4+CiStM2 8.21 + 3.14 GOE = 11.35
Thanks to both teams for earning three spots for 2027 Worlds.
