Belbin / Agosto had the same 'powerful fed and media backing' but they never won a World Championship. If D/W were mediocre, what does that say about V/M at the time, who finished 2nd to D/W for the last two years of that quadrennial?
Belbin/Agosto were even worse and won an OSM and multiple world medals. There's your 'powerful fed and media backing'.
It says that V/M were never scored adequately for their far superior skating skills while D/W got to be mediocre and still be rewarded for it.
