Please excuse my ignorance, I had thought that those spots had disappeared during Covid.

It does make sense, knowing how much danger is inherent in pairs skating, for it to have smaller warmup groups than in ice dance.
I admittedly miss the days of more top-level pairs teams, but it isn't as if the mid-level teams aren't worthy of being watched; they still bring their own type of excitement with them. I simply hope more of them can be seen on the Grand Prix (and there's still some TBD slots...).

Perhaps more Challenger events for pairs would help?
