When the rules change, D/W and S/S will change the style of program they are doing. There is nothing that either team is doing that deserves to be punished.
OTOH, having both team members fall during a critical skill has always been "punished", either under the old system or the new system. For example, B&K falling at the 2002 Olympics during their final required lift. So P&B would have been dropped like a stone at Worlds in either rules regimen. In COP, the Shibs benefited. Under the old regime, probably Bobrova & Solviev, who finished fifth last year, would have benefited, because they were not rookies like the Shibutanis, and the old system very seldom rewarded teams in their rookie season.
