Regular - 1000 rpm rpm
Pool cleaner - 2000 rpm
Spa - 2500 rpm
Max - 3450 rpm

I can even combine pool cleaner and spa.
Setting are now

Regular - 1200 rpm rpm
Pool cleaner - 2600 rpm
Spa - 2600 rpm
Max - 3450 rpm

Power as indicated on the pump is 10-12% lower than in the Hayward calculator. This may be occurring because I have a larger cartridge filter and it is recently cleaned. Pressure gauge at the filter is reading around 6 PSIG (15 ft head) at 2600 RPM. From the pump flow diagram, this would indicate about 95 GPM flow.

I need to get my Fluke current meter and verify the power readings.
