Building The Perfect Track

I want to build a mathematically perfect mountainboard track. It would include all the knowledge we’ve gained from thinking about how tracks should be built.

It would use a clinometer to ensure the track always runs at a constant angle, the rollers would be built using a sine wave with a 7:1 ratio, and the berms would be laid out using constant curves and radii.

Laying out the perfect berm

All I need is a hill and the time.
