Except the Cateye's sensor is a simple magnetic reed switch; there is no
"induced spike", just a contact closure that will not be significantly
dependent on the speed of the passing magnet. (The only computers I am
aware of that do depend on induced signals are the Avocets, and they use
a 20-pole magnet ring mounted at the hub.)
Responding to the original poster, if there is no limitation to where
you have to put the wheel magnet (IIRC some Cateyes had a magnet carrier
which wrapped around two spokes, so the magnet and sensor had to go
about mid-wheel), I'd put it as close to the hub as you can get it,
mostly because that lets you tuck the sensor in back of the fork blade
instead of having it stick out toward the spokes.
