You are right, it doesn't say much. I am just saying that you could argue about Pall, but its just based on a lot of unknowns so it doesn't have any use.
Oh and about that Tulak thing, come on he would have to have been pretty powerful to survive and be called the greatest duellist ever. He would not be that if he didn't have a great command over the force. Nothing near Ragnos probably because if he did he would be more known, but thats not really the point.
