Anyone can tell you that, and you can look under a microscope and see it. In the context of skis use on race courses it shouldn't matter, because you're probably not going to hit anything that will damage the edges and the tune intervals are much shorter. You could quantify that there was more wear with more angle with an electron microscope, but does it matter? Probably not.
I wouldn't call a 3 degree sidewall radical, I used to sharpen my snowboard to that.
No doubt there is a relationship between how acute the edge is and how fast it wears, however it is probably more like a sinusoidal curve than a straight line, flattening out near 90 degrees, and getting very steep near zero degrees.
I like 0.5, 3 on my SL, GS, and 0.5, 2 on my antique speed skis (the way Kästle set them up -trying to get back to the original just peeled the sticky tape off the base tune LOL). 1,2 on my mogul skis. Machetes are now 1,1 because they came with a 1 degree base which hasn't seen a grind yet, and because the cap won't let me put the sides at 2 degrees anymore.
If you are skiing powder or deep soft snow of any consistancy, it doesn't make much difference, so you may as well put a a hard-snow tune on 'em for when you come across a patch of icy, wind-blown or refrozen snow.
