But I believe we more or less wrote the same, although you had a good explanation as to why it is that way
"You could blast a ridiculous amount of water through the cooler with only a slight difference in temperature and still cool it more than a lower flow with a higher temperature difference."
To clarify, the temperature difference referred to is between water going in and out of cooler. Not the one between coolant and wort.

More specifically what I was wondering was if you had any thoughts about making those measurements mentioned above and comparing the results?
I started to try and elaborate here but I lost track, not sure what you'd get out of comparing that in the end. But jaginger seemed to like the idea.
