It's interesting.I think Russian nationals could be better than worlds unless a lot of people skip it. IMO some of the Russian JR girls are as good or better than the foreign competition that will be at Worlds.
Gracie would be potential RN medal favourite over Pog, Tuk and all juniors, but who else except her?
So, Worlds vs RNs competitiveness would come to simple question: is lone Gracie a bigger medal threat to Sot,Lip,Rad than ~6 top-ten Russian skaters?
Theoretically, in perfect circumstances (if she was uber-consistent) she is, but in real world numbers prevail I think - let's say she makes a mistake and just one of those 6 (who are very good skaters anyway) performs skate of their lives...
It's all about probability, I wonder what'd the oddmakers say?
