This has appliances already calculated for you.
For appliances like a ducted heater that may only cut in for 4 minutes, 4 times an hour. You can use the third field to reduce the hourly rate. That way when you log an entire hour for that appliance it would be like logging 16 minutes. Using the reduced rate you'd only have to log the hours from when you turn it on in the morning until the time you turn it off, even though some of the time the system is in idle mode.
