I'm not sure I'm following what you're trying to say.

The PQ curve for the pump is replicated from the Laing site. There may be some very small variations in the translation from their graph to mine. Laing have more straight-lined some sections, while I applied a measure of smoothing to the curve which is what we would really see if we plotted the PQ curve to 0.1LPM increments.

The separate curves for the system include the pressure drop of the radiator, the waterblock, the tubing, and the fittings. Where the curves intersect with the pump curve is the flow-rate that we will see.

The nature of the curves are such that if there's any errors in transcription that it affects all points equally, so while the results may alter by a few 0.01C points either way (inherent margins of error) the relative differences between each data point should be fairly fixed.
