Maybe Weir still fails to understand how to use CoP for artistic performances? I mean the way e.g. Buttle (and his choreographer) do.
Exactly. There have been great artistic programs under CoP in just the last five seasons, choreographed by Wilson, Dickson, Browning, Linichuk,Tarasova, Morozov, Petukhov, Zhulin, Moskvina (for B/C), Steuer, Spilband, Zoueva, Dean, Karahawa, whoever of "M. Colberg, H. Wiesinger, A. Kapranova" choreographed Othman's LP this year, Bruenner (now Guadarrama), and Nichol that are the equal to any triple/quad-era programs under 6.0.
In addition, when Tarasova choreographed Weir's programs last season, he took the advice of the USFS review panel that decided his elements weren't difficult enough, and he changed them. (I don't know who was on the panel, but, on the whole, USFS was behind the curve in learning the system.) As I wrote last year, if had done all of the jump elements he's allowed, instead of leaving out combinations and jumps, he could have done the allegedly L2 spins and footwork and have retained the same base score. And under 6.0, had he done 7 instead of 8 jumping passes, it is highly unlikely that he would have made the podium, especially without a quad. When he could do his "easier" spins and more "artistic" footwork under 6.0, in Dortmund, for example, he still didn't do all 8 jumping passes. (All of the men on the podium landed quads, and so did 4th place Lambiel.) If CoP hadn't made it worth doing a 3/3 in the SP instead of the quad, had his competition attempted and landed the quad or quad combo in the SP in Torino, it is highly unlikely that he would have been second after the SP. It's not CoP that is sinking him: it plays to his strengths -- at least until this year, he had pristine jumping technique -- and levels most of his weaknesses.
All of the top coaches in Russia have complained about CoP. I'm not surprised he's on that bandwagon.
