We can endlessy discuss of how much difference there is in various PCS between two or more given skaters but that's not the point (i.e. forget Aliona and Sasha for now)
TES score difference between skaters of the first group (top of the top) could be as much as 40 points.
If you're impying that a clear difference in PCS between two hipotetical skaters should not worth 1/3 of said TES difference, then we can abolish PCS and finally "upgrade" figure skating to barrel jumping.
I would most probably watch an acrobatic jumping competition on skates (it would be superfun), but it's not figure skating.
Figure skating is chasing an impossible balance between the athletic and the artistic components of the performance.
I don't expect the same amount of difference in PCS as there could be in TES, especially in a moment where the jumps are evolving, but both TES and PCS should be crucial to the final score.
There is no connection here. mix different things.
The difference in TEC can be even twofold or more, it really exists. So what? What balance can there be?
If you want to see the triumph of beautiful ice skating over ugly Ultra C programs - make the PC factor for lady 2.0 instead of 0.8. And soon no one will bother you with quadruple jumps.
