it goes in and on. it's pretty obvious to the touch when your board needs to be waxed.
and for what it's worth, wax isn't used for "abrasion resistance," it's actually there to increase friction to melt the snow faster. you're essentially hydroplaning on a thin layer of water between your board and the snow. the grooves allow the water to flow freely, reducing drag.
anyway, i don't claim to be an expert. i'm just repeating what every guide out there says. who knows. maybe they're all wrong and you're right.
