My tool is just a collation of results posted by others, and I link to them for perusal of their techniques and equipment. I don't do modelling of radiators/blocks/pumps using mega tricky, brain implosion formulae like those in this post. I just use published PQ graphs to derive a PQ equation (flow vs head), and a published C/W graph to make a CW formulae (liq flow vs delta-T). For pumps, I assume 60% to 80% of the rated wattage goes into the coolant as heat depending on flow rate except if pump is submersed, then 100%. I've seen a recent pump test including wattage info, so this may be refined.

For radiator data, I use one tester (there is only one!) but was looking to combine two era's of testing until a single block of data is published (waiting with abaited breath).
For block data, I use one tester and will link to that review once I confirm they're "happy" (ie: not going to sue etc).
For pump PQ, currently using manufacturer (marketing dept?) graphs, but hopefully this will change "any minute now" as per previous.

I don't see the problem with combining a single set of block results with a single set of rad results and, ideally, a single set of pump results.
