I don't think they have it yet and with this ridiculous GOE range any advantage they have technically could easily be nullified for a team that gives the judges more feels.
Typically speaking, GOE & PCS tend to drop regardless. At least that was the result I got when I compared the three highest-scoring & highest-placing transitioning teams' scores a couple seasons ago. (Even the Shibs and Papadakis & Cizeron's GOE was limited during their debut seasons). This season such a comparison would be pointless because the range has changed between last year & this year, but we can compare the GOE for top teams that just started seniors with the GOE for the top junior teams this season--who have never defeated those transitioning senior teams.
Even at Tallinn Trophy, where scoring was more generous than on the GP, Carreira & Ponomarenko earned 0 plus 4s in the RD and 3 in the FD. Skoptcova & Aleshin, whose scores were much higher at Tallinn than elsewhere this season, earned 2 plus 4s in the RD and 8 plus 4s in the FD.
At Junior Worlds, Lajoie & Lagha earned 12 plus 4s in the RD and 24 plus 4s and 3 plus 5s in the FD.
Khudaberdieva & Nazarov earned 5 plus 4s in the RD and 8 plus 4s and 1 plus 5 in the FD.
Shevechenko & Eremenko earned 5 plus 4s and 1 plus 5 in the RD and 9 plus 4s and 3 plus 5s in the FD.
Nguyen & Kolesnik earned 10 plus 4s and 5 plus 5s in the FD.
Ushakova & Nekrasov earned 8 plus 4s and 1 plus 5 in the RD and 11 plus 4s and 1 plus 5 in the FD.
That kind of GOE just isn't given to transitioning senior teams.
