I have to add that winning 12 straight 5-point matches against GNUBG in a level of more than Advanced (Expert or more) would make you the best Backgammon player on the galaxy with a huge difference from the 2nd. With few words: It's impossible! So i guess you played with Intermediate or something like that........
