1. A method for reducing power consumption in an implantable stimulation device, the implantable stimulation device delivering a repeating pattern of pulses to one or more tissues in vivo, the method comprising: dropping one or more pulses in the repeating pattern of pulses; and counting with a drop counter each of the one or more pulses dropped to determine completion of a dropped set within the repeating pattern of pulses when a number of dropped pulsed equals a drop parameter.
