One way to overcome the whole test with this setup or that setup is to test each block with varied amounts of pumping power. Maybe something like the delta T between water and core average vs Water Horsepower. You could then label specific points of water horsepower to identify specific pumps like one D5, one DDC with top, two DDC's.
Here is the water horsepower equation,

all you need is the pressure drop at the block and the flow rate. And if you already have the pressure drop curve, then all you need is the as tested flow rate and you should be able to convert this data and simply test at several flow rates.
Then you could compare the blocks fairly over this water horspower axis and see the complete picture in how pumping power affects performance and where the optimizations are. It's more work and may make it more difficult to understand, but it would provide the data to answer all the "What if I had x pumping power" types of questions. It would be kind of like a c/w vs flow rate, but something better in regards to using pumping power instead of flow rate. Using flow rate will inherently favor the more restrictive blocks, but using pumping water horsepower should fix that problem. Also using delta T (core-water) is something a bit easier to picture than c/w.
Anyhow, that's something I've always wanted to try, but never got around to it.
