My argument was that the higher the flow, the more heat a radiator dissipates. I was correct. I also stated that the hotter a radiator is, the more heat it dissipates, I am still correct, as shown by the graphs YOU presented.

Also, I said "unless you get to extremes"... as you will read from MANY sources, here and elsewhere, anything below 1.5GPM you should start worrying about how to increase flow rate... meaning 0.5GPM is an extreme.

Again, you have lost sight of the argument you were trying to make, and are now arguing semantics.

Show me proof that lower flow rates are more efficient in a radiator than higher flow rates, because you still have not done so.
