Nice! Maybe as a suppliment create a complimentary pumping power based chart where the X axis is pump setting instead of flow rate. I like seeing the flow rate too for estimating purposes, but for comparison prefer leaving X in some sort of pump power unit. Using flow rate only will make the more restrictive blocka look better since the curves stay to the left and lower than lower restriction blocks. That could be useful in comparing amore complex loop, but its also very possible to have a lower dT with the low restriction block produce a curve further right and most users will interperet lower being better at like flow rates essetially fixing the flow in their head and completely missing the pump power data points being shifted along the X axis. The problem is that comparison is two different pumping powers. That's the problem I have with comparison of dT vs flow rate charts. They have all the data correct but hard for most users to read without automatically comparing at equal flow rates. I think that is why Vapor produced both types of charts...one where X is flow and another where x is pump power. I have also seen Cathar convert pump power to energy as another means to fix this problem.

Anyhow, very cool. My hat is off to you for having the patience to evaluate pumping/flow sensitivity. This is one thing that is much easier to do with IX as trying to do 5 mounts using paste over many flow rates is time prohibitive...at least for my level of patience which gets smaller and smaller as I get older..lol

Great work!!
