The new edge rule will harm a lip about 1.59 points (30% deduction). And BV for 3F is 5.3.
Not to mention, YuUru does not get the e call on every flip he execute, it's about 7/13 flips he get the e call. So if he manage to fix his Flip this season, other guys have to wish for him to make terrible mistake.
Yuzuru's new BV is 95, if he is clean with that insane layout, a lip costs him not much. So yes, to challenge him, other guys need 2 different quads in their arsenal. After all you can't just wait for other competitors to make mistake. What if your competitors make no mistake at all? To skate your best is the only choice.
