R&H and O&W aren't on the list simply because neither team has the TES minimun scores. (SD score for both IIRC).
I think that's what blue_idealist and I were wondering above, but I assumed that since both had gotten solid scores at 4 Continents in January that they must have qualified for Worlds. R&H finished in 4th at 4CC's - just one spot off the podium. I assumed these teams had high enough TES scores for Worlds, but I guess I was wrong.
Thanks for the info. I guess this shows both teams need to raise their game because at this stage in their careers it's not good to be having trouble making the TES minimum for Worlds.
