Profiling Options for La Marzocco GS3

The algorithm motorValue = (((flowTime * X) - (totalFlowCount * Y) + Z) / 10) has three parts: - The flow dependent part (flowTime * X) which increase the motor value if time between flowmeter readings increases or vice versa. - The progress dependent part (- totalFlowCount * Y) is, in this case, us...
