If your Spiral isn't Level 4, you only get half as many points for positive GOE.
IMO, it should be a +1 bonus for ALL levels. Even still, doesn't it feel wrong that the best Spirals we've ever seen (from Arakawa and Cohen) are now only Level 3?
I am really worried about what some of the spirals are going to look like! And yes, it does seem hard to believe that Arakawa's and Cohen's sprial sequences are now 'only' level 3. But, I'm a bit slow in learning and accepting parts of the new system, so I still can't believe that the Kwan smiral is basically a thing of the past (and not just because Michelle isn't skating - a long steady, fast, coe spiral doesn't even seem to be a worthy goal anymore )
