I'm a huge rollercoaster nerd (yes that's a thing, I recognized nearly all of the exemplary rollercoasters by name or by manufacturer) so I already knew this but it's a nice explanation. Any other enthusiasts?
Enthusiast checking in. It is a nice explanation. Something I haven't seen on the internet yet [outside of some posts about the NoLimits editor years ago] is the physics going into some of the newer elements used by Intamin, S&S, and the like.
