Obviously this is a question that bears analysis.
However, I think there is often not as much variance in scoring across events as we might think. (Just as one example, Hawayek/Baker last year received virtually the same PCS in the free dance at WTT as they did at Worlds, it was just .02 apart.)
But here's a quick look at what several teams have scored for their rhythm dances across several competitions this year:
In their 3 competitions so far, Hubbell/Donohue have scored in the rhythm dance: 84.06, 83.58, 84.79
Chock/Bates: 83.72, 82.55, 86.02
Papadakis/Cizeron: 85.58, 87.45, 89.08
Green/Parsons: 65.78, 73.93, 72.40, 75.60, 75.35
Smart/Diaz: 75.20, 74.06, 76.97
Hurtado/Khaliavan: 72.65, 74.79, 76.40
