I just went back and did some new combinations with early ones and I'm still getting intermittent delays even though all early combinations must be done, so I assume part of this is just the server itself being a little overloaded and so even responses that are cached remotely but not locally may experience delays.
oh I just realized that 'isNew' in the response refers to a global set, not the user set. So, I guess it's doing exactly what I said lol.
