Not really. In singles only top 24 skaters make it through - there's still a cut off. You can see this from 2014-2020. The reason why we haven't seen skaters miss out lately is because there aren't enough competitors. Hence the three spots per country. If they lost spots, the competition would be even smaller.4CC isn’t the equivalent of Europeans, but I think it’s more competitive in three disciplines, pairs being the odd man out. But Europeans is the more elite competition.
Fans like to say the issue with 4CC is the timing and travel, but I say there’s more to it than that. For one, at 4CC all skaters make the free skate, regardless of how poorly they do. And every country gets three spots regardless of how poorly the skaters do. There’s no such thing as losing or gaining spots. If a country has enough skaters with tech minimums, they can send three skaters every year. That is the real issue. If there was actually something on the line then you best believe federations would send their best skaters out.
