here are the score sheets from GPF and French Nationals so you can compare Gaby/Guillaume, C/B and W/P's programs.
SD:
France -
GPF
FD:
France GPF
Even if we ignore the GOEs that might be inflated, it gives an idea of the elements and of the levels they get. Verdict: they are all pretty even. Gaby and Guillaume will also get strong GOEs in international events, given they are world champs but also given their elements are extremely well done and refined, so they deserve them.
About errors, Gabriella and Guillaume lost 2 levels on the twizzles in the FD (which we will see if it is a one time error or a more important problem with next competitions) and they had a problem on the pattern in the SD with a "N" at a keypoint (same as twizzles). But C/B also had problems with their twizzles at GPF and even W/P struggled on them (which was not reflected at all in the notation btw). I also think C/B had problems with their patterns throughout the GP series? I am not sure anymore.
As general impression, I think Gaby and Guillaume skated too far appart at the French nationals and they will have to get closer when on hold in the footwork. I also feel in the SP, the transition from waltz to march with the same music but added march rhythm is a bit awkward. But their skating skills are the best imho. They have effortless glide and speed, good edgework and very pretty positionning and extensions. As for interpretation/ execution, I personally feel that their connection with each other and their musicality is the best as well among the top teams. They also have an intangible it factor that make them so sexy and magnetic to look at.
Conclusion, I don't think Gaby and Guillaume are out of contention at all for world podium and even a second title. We will see. But I disagree it is a given for W/P and heaven forbid C/B that they are gonna win.
