tach pulse count

I am putting in an Isspro tach and plan on using a factory tach sensor.The Isspro tach uses dip switches to adjust the calibration based upon number of pulses per revolution.Does anyone know how many teeth are on the IP gear? I read somewhere it was around 106 ? That seems like a lot.based on that number the pulses would be 1/2 ? (53) .

Am I correct in thinking that the pulses would be half that number...does the ip turn 1/2 engine speed like a cam or distributor would?
