0g Score Possible?

[3D Anvil]

A knife sharpening outfit called Burrbenders has several videos out showing a BESS score of ZERO, and others with scores <5g.  Is this even possible, assuming the test media is real and the test is being done correctly?  In the video the guy doing the test isn't using the fulcrum, and he's moving too quickly, but even then, a 0 score is mind boggling.
