Right, I should have explained further: I would bet that the quantum
steps seen in the graph are equivalent to the smallest measurable
value, (0.0001 / 60) of a minute. From that you can count the number
of steps, multiply and get his drift. The vertical quanta are easier
to see and count than the horizontal ones.
