First, they lost the medal in the short dance, where their performance were also the worst in the season,
Second, since they had a good free dance, with which they won silver and bronze at the World Championships in previous years (with the result from 2023 it would be another silver today), why experiment and invent something new? You don't change what works well - better is the enemy of good,
The facts are that the Italian pair achieved a worse result at the World Championships than at the European Championships and generally had a weak season, and assuming the return of strong Russians, to win a medal they will need to score around 216-217 points, or maybe more.
