As a National Coach myself, i wasn't asked if Marin should implement this system to NTs. It wasn't in the discussion, we preferred to focus our resources (time) to implement it without NTs. Would it be there in the future? I don't know. As a NT coach myself, i see how it'd contribute, but perhaps there would be other, more important features and updates for everyone.
But why did the “impossible team,” playing with the same lineup and the same tactics, have different ratings in each match?
