The system further including a control circuit configured to control actuation of the plurality of valves. The system can operate in a first mode and a second mode. Wherein operating in a first mode includes opening valves according to a first valve actuation pattern and operating in a second mode includes opening valves according to a second valve actuation pattern. The system can be configured to periodically switch from the first mode to the second mode and compare the efficacy of the two modes. Other embodiments are also included herein.
