T&T: Advice on Equalizing & Tachometer?

[Dave Cooper]

<Arild wrote in part: Remember more pulses per revolution is better.>

I keep seeing this statement but I don't quite understand why it is true. 

Any resolution better than 1 revolution would seem to be overkill in any
mechanical controlled engine. I can see the need for much greater accuracy
of where the engine is in the cycle for valve or injector timing on ECU
engines and so the need to count teeth in the ring gear, etc.

However, for a tach intended to be read by us humans 1 rpm should be
accurate enough. One pulse per rotation should give this accuracy, IMO. 

As always YMMV...
