I haven't checked that link, but it's a sure mix of height, weight and do not forget ability. I have my DINs on pretty much the max they'll go on, but only as I do not want to lose a ski on most the stuff I'm doing.
So if you're tall and heavy you'll need them higher, but if you're useless also, you'll need to lower it so they do pop when you hit the deck. etc etc etc
