If the laser light stays in exactly the same place on the wall as the platter rotates but the "line" created by the laser beam gets longer, then it is at least possible that the tt is momentarily gaining speed above 33 rpm (assuming the flash of the laser is of constant duration, which is a fair assumption). But the fact that the light does not move left or right indicates that "average" speed is maintained. This is one explanation that comes to my mind; I have no idea what you are thinking, Albert and Henry. I would be interested to know.
It seems to me if the tt slows down momentarily, the laser spot would shrink, not lengthen.
Albert, I take all your points in support of the NVS, but the bottom line is what do you think of it in action? Does it blow away your SP10 Mk3?
