which is exactly the basis for this whole exercise
at 3 gpm and 150W I'm looking at a deltaT of 0.20°C, so at 10W the expected deltaT would be 0.0133°C
at a more reasonable/measurable flow rate of 1.5 gpm the deltaT is 0.38°C, so 10W would be ~ 0.0253°C
I would not be too uncomfortable at differentiating between 5W differences, but lesser increments would not be 'measurable' with the equipment I have
next time I'm into pump testing I'll gin out some measured values
