code: def _updateMinDutyCyclesGlobal(self):
      
      self._minOverlapDutyCycles.fill(
          self._minPctOverlapDutyCycles * self._overlapDutyCycles.max()
        )
docs: Updates the minimum duty cycles in a global fashion. Sets the minimum duty
      cycles for the overlap all columns to be a percent of the maximum in the
      region, specified by minPctOverlapDutyCycle. Functionality it is equivalent
      to _updateMinDutyCyclesLocal, but this function exploits the globality of
      the computation to perform it in a straightforward, and efficient manner.
