It should be easy to calculate given the metamodel, right?

Same for correlation with the metamodel.  
Numerai has the metamodel. It should be easy to calculate.

There was talk in the last fireside about getting this done (at least a TC estimator based on historical metamodel – no reason metacorr shouldn’t be included with that).
