I found very little value in the measure, since you're just pressing a spring into a soft material there's so many variables I could get a 10 point swing based on how I pressed the durometer into the rubber (super quick vs super slow). You could also take some rock hard tires that have sat over the winter, go heat cycle/scrub them and they'd get five points softer.

It'd be invaluable if you had to pick out some unlabeled tires from a stock or you get to pick a cart at the local rental place, with enough careful notes and experiences with a certain compound you might be able to predict some characteristics, but I'm not sure the duro adds a lot more to the notes. idk been a long time since I played with one consistently.
