First a quick clear-cut question: when making fin adjustments to the thousandths, is it only ever in increments of .005" (so the final measurement ends up at .xx0" or .xx5"), or are there people ending up with measurements like .xx3"?
Then the real question: I am fairly new to course skiing, and have yet to learn much about fin adjustments, but I certainly plan to, as I really like the gear/tech side of things.
But I have to confess: I don't understand how moving a fin .001" or even .005" could make a difference in performance. An average human hair is about .003." So we're talking an adjustment of roughly the width of a single strand of hair… intuitively, it just doesn't make sense to me.
I am curious to hear people's subjective opinions, but most especially if there's any definitive "lab testing" that shows what difference, if any, can come from such a tiny adjustment. And maybe a scientific explanation to replace my unscientific intuition of how that's possible.
