I'd agree with previous posts that pickup position counts for a fair bit.

FWIW, measured from the nut, the centreline of a Jazz bridge pickup (60s position) is 80cm and the centreline of the bridge coil of the MM is 79cm. Coil tapping the MM should be pretty close in terms of position but the bigger magnets and windings will also affect the resonant peak and tone.
