CBC commentary for their Rostelecom Cup LP is at 1:01 (the password is pairs): https://vimeo.com/299711278 Their SP wasn't broadcast on Canadian television.
It seems that Efimova / Korovin will not get a 2nd GP event unless someone WD and E/K will be chosen to replace them because it should be very much given that Stolbova / Novoselov will get the last Rostelecom spot.
After winning a GP silver last year and almost making it to the GP Final one could have thought that they would get two GP events this season but obviously this was not the case.
