Let me also add that multiple magnets would definitely *help* the
process, if an F/V method were used. My point was simply that any
rate of discrete events can be smoothly counted, if you don't care
about the accuracy between those events. If you really need
resolution (like with control systems), go with a rotary encoder.

1. A sensor
that can measure my cadence. A simple magnet switch that
triggers once a revolution won't be enough to measure the cadence with
sufficient resolution, since my cadence is usually between 50 and 80
rpm. I would probably need to mount multiple magnets spaced equally
around the chainwheel and have a single sensor on the frame. Then I have
to get it to supply this information to my control program.
Once per revolution is okay. b/c what you've really asked for it not
that the estimation be accurate to some threshold throughout the
cycle, but that the output be smooth and continuous.
