With wasted spark, you should see the same amount of pulses.  All it =20
really does is tie two plugs to one point on the distributor, so the =20
spark pulse on a cylinder's exhaust stroke is the same as on another =20
cylinder's compression stroke, and hence it does not affect the number =20
of pulses seen at the ignition coil.  It's done to simplify the system =20
(less components).
