I am looking at the protocols right now and all the K/S spins are level 4, death spiral is level 1 indeed. It seems that they simply lost on GOE.K/S reportedly only had levels 1 on their SBS spins and the death spiral. Their jump landings were not good either, so they lost it by not getting their levels and being scratchy. They had the opportunity to win it on TES, but they didn't take it.
S/S had one really huge mistake, but their performance quality was excellent, and the lifts, throws and other elements were going to get huge GOE.
