It plainly states that you can add statistics to the tree based on an external database and you don't actually have to add the game lines to the tree. The submenu is Edit/OpeningsBook/LearnFromDatabase However that was not the focus of my original post. My original post clearly stated that sometimes when adding a move to the tree, the tree will add bogus statistics to the move even if no retro move shows from a possible transposition. I have the retro moves feature turned on.
