Math is extremely simple. All you need is rider mass, drag factor (aka fudge factor - start at 0.3 and dither) and velocity vector at the lip. It is literally a physics 101 homework problem. Can be done with or without differential equations - technically, it’s still a differential equation, but the solution is pretty commonly used on it’s own…
That is really hard to do with Austrian Techno blasting in the background while ripping lines of coke.
