Relationship of daily round correlations to final round correlations

The first part of your question is unclear to me, but it sounds like you may have a misunderstanding of what the scores mean. In any case, can you re-phrase or give an example so we are sure what you are talking about?

And as far as the API, again not sure what you are referring to? (I pull the scores from the API every day no problem. We are talking about the Numerai tournament, not signals, right?)
