I would try the ring test on several known good (B/W is ok) flyback transformers to get an idea what the display should look like... I agree that that seems to fall short of the 10 ring threshold, but what does another flyback do in your set-up? Perhaps the scope input impedance is lower than that in the tester circuit, causing more rapid damping?
