I'm not sure if I can post this here. But we'll try.
Here is a link to TR, you may have to purchase his actual research papers (I'm not sure if he puts them on his web), but could could try chatting with him in his forum. Tell him BobCo19-65 sent you from here. He is a very knowledgeable and honest person and has spent tons of time doing actual research in the field.
