I wouldn't put much as much weight on the result of an offseason exhibition as I would an olympic finals appearance and a world bronze the year prior. Not saying Carr can't repeat the result, just that it doesn't carry as much weight as it would if it were to have happened at a rankings tourney.
ETA: Takahashi is competing for Japan this year. Carr beat 2x medalist Daichi Takatani. My comment remains the same.
