Well done!
While accuracy is generally a good thing, I don't think you need to worry too much. Between hand strength, brake track surfaces, weather, pads, compression of casings etc etc there are so many other variables that I think you've done enough. This would be a be a good chart to indicate which combos that are good, possible and hopeless matches.
I've long suspected that brake part matching mostly isn't an either/or scenario anyways.
Back when I took a more active interest, I determined the (added) pull of a Travel Agent and compared it to the difference in pull between the Canti/Caliper levers and V-brake levers that I had available. And despite TAs being generally considered quite OK, it wasn't a close match.
