The only way for the Quads to not become 100% mandatory, though, is for the PCS to be scored correctly. You have to win the competition on PCS if you can't win it technically. That's why overscoring is such a huge problem. If you give a Quad skater a 9 for Performance/Choreography/Interpretation when they really deserve an 8 or less, then there is no room for a masterful program and performance without a Quad to ever win.

For example, I think Jeremy Abbott's performance at the 2008 GPF would have deserved to beat Patrick Chan's at 2011 Worlds. That never would have happened with the way the judges hand out their scores, though. And the scoring system itself is still flawed because mistakes on jumps are not penalized enough. The -GOE deductions need to be increased.
