Ah! so if I have the values so that with the stick centred I get:

N = 1, S = 1, W = 1, E = 1

then when I move the stick north I should have:

N = 0, S = 2, W = 1.4142, E = 1.4142

because I'm calculating the hypotenuse of a triangle between the centre,
the stick position and the oscillator.  That makes more sense.
