Everything should be looked at in context. 201 is a good score for juniors. In fact it was the second best score ever. Still it was not enough for Marin to win JWC because Alina had 207. 188 might be a good score but who would care if Kihira were clean with 2 3As scoring around 200? And it is quite safe to say that Samodurova was lucky to win trailing behind Tarakanova who scored 196 just 2 weeks ago with the free score of 130 vs. Sofia's 125. Yes, they deserved to win but they were lucky unlike Trusova and Tarakanova who were dominant at their events.
I would care because 188 points should be enough for Sofia so that she would make it to the JGP final. Nowadays one doesn't make it to the final unless one has scored good scores. Good scores doesn't always give you the victory but it is something that is enough to win some events and to get on the podium in most events. Even great scores doesn't get you to the center of the podium every time, just ask Dasha. She was clearly very disappointed that she didn't win despite the great score.
