Looking back over the thread, one thing I neglected was that you have a top mount filter with a backwash valve. Those valves tend to have fairly high head loss and half of that is before the filter gauge so it is not part of the filter pressure. Anyway if I include that and the suction side plumbing setup including the 3-way valve, here is what I get as an operating point:

Flow Rate (GPM) 69
Head Loss (ft) 65
Energy Use (Watts) 1,839
Energy Factor (Gallons per Watt-Hr) 2.26


Here is the break down of head:

Suction plumbing: 6' = 4' of dynamic head + 2' of static head
Pre-filter backwash valve (1/2): 10' dynamic head
Return plumbing: 49' = 51' of dynamic head - 2' of static head

Hopefully everything is included this time. If you want any more accuracy, you are going to have to take a suction measurement at the pump.
