A tapestry of fib relationships is often most effident in very good powder skiers when they porpuse in & out of the snow. The holes left will often be shell shaped i.e., the turn shape will be spiraled shape as well as the porpuse out of the snow. ( has the right look based on eye only)
From my experience I find it the most fun when the distance traveled .618 out of the snow & .382% of the distance traveled in the snow. (of course snow conditions must be ideal & I find it best if the ski is softer in tip then tail bending is spiral shape) Measuring from the bottom of the porpuse to the bottom of the next porpuse ( only by eye) seams to form the golden rectangle.
It would not surprise me the snow density increases based on fib from top to bottom, the speed of which the leg extends seams to be based on fib as is evidenced by nautilus strength training equipment which is designed to follow the natural strength path of the body. the fingers is composed of 3 bones in golden section to one another, takes the spiral shape when curled which allows one to pole swing a spiral shape if using three small fingers for triger fingers. There are other fib relationships found in the body which some how seam to allow to my eye perfect shell shaped holes to be made when skiing.
I will often see a tapestry of fib relationships in skiers tracks & I dont think they were trying to make them.
I could be wrong regarding music, I got the info from a book
