The worst case scenario is pretty much unbounded. 80mph range will be worse than 70mph. But it's still better than range at 90mph or 100mph.
I guess you could use the highest legal speed limit in the US alongside the lowest temp and fastest headwinds ever recorded in Texas. In conjunction with the heaviest, least aerodynamic thing that the vehicle can physically tow.
But that may be annoying to replicate in a controlled setting and will be even less relevant to most people than the EPA distance.
