When I tried to imagine solving this, I was pretty concerned about a variable that was not mentioned in the post:
I worried that a hotwheels track might not fit a sphere snugly enough to ensure the sphere would exit the ramp traveling at a consistent yaw, and so you’d need to worry about angle and not just velocity.
I did not come up with any way to deal with this if it turned out to be an issue.

I was also thinking of this but from the experiments that were run it seems it was clear enough that it was not a problem.
