My thinking was that the TR value are given by the player's skills with tactics and are part of the initial calculations of coefficients (the intial calculations would also include also the venue, PR specialty, enthusiasm, the attitude, GPD...). Then those coefficients are used in the GE for the subsequent calculations - basically the player's skills matchups in the events we see in the play-by-play. You are saying that TR are only a statistical category you see after the game in the box score, did I understand you correctly?
